A Third Eye on Technology

For those of you who don’t know, Steam is an online game store and distribution platform that is a product of a gaming developer called Valve.  Valve has been know for creating several very popular gaming franchises such as the Half Life series, Left 4 Dead, Portal and Team Fortress among a couple of others.  Steam is their online store/software client that gives consumers ability to purchase and install over 1,500 games from other developers alongside their own games.  The key features of Steam are ease of use and the ability to keep games you’ve purchased linked with your user account, so games you’ve bought are yours forever and will carry along with your User ID for years and years without any need to keep track of installation CDs or key codes to install the game, not to mention automatically download and install updates for every game you have automatically and cloud sync save-game data between different computers (if supported by the game itself, and many games do). Oh, and they have a tendency to throw incredible sales campaigns from time to time that will net you some of the most popular games on the market for next to nothing.

Recently, Valve made an announcement that it will be porting Steam to Linux (with official support for Ubuntu Linux in particular) and is entering the Beta Testing phase as I write this.  This has a lot of buzz going on in the Linux community of course and there is a lot of speculation about why Valve is deciding to do this.  After all, there are a lot of software development companies out there right now with major product lines (games and productivity software) that could have ported their products over to Linux (or even Mac for that matter) but very often decide against doing so because in most cases it wouldn’t be worth the effort.  Linux is the third most popular operating system in the world and it’s a far distant third at that.  Putting money towards developing native ports of their complex programs probably wouldn’t pay off because the user base (and the number of paying customers in those markets) is small, introducing risk with doing something like deciding to invest in Linux as an officially supported platform.

In a likeness to the way Steam works, Microsoft’s Windows 8 is going to have its own integrated “app store” built into the OS, just like an app store is on any smart phone or iMac (or Ubuntu, for that matter).  However, I don’t think it will necessarily prove to be something that will lure  current Steam users away. In the future there might be a group of new users who associate such an app store as being the best place to shop for things like games and other software and come to believe that competing app-stores (if they’re even aware of them) are inferior, but I don’t think that is Valve’s primary concern.  Sure, it will be great to see Ubuntu (and other Linux distributions) having Steam running naively and for its games to outperform Windows-based systems (which has already been demonstrated by Valve in benchmark tests when comparing the two OSs), but I don’t think Valve is looking to diversify Steam on to Linux simply because they think more people are going to outright switch over to Ubuntu on their PCs because they’re looking for an alternative to Windows 8 or because users are looking for a small boost in performance.  There are a lot of benefits to using Linux instead of Windows, like not having to worry about getting a virus on your system or a majority of the software being completely free (because it’s open source).  While all of that is attractive I have another theory that goes beyond users simply adopting Linux, one that has very little to do with Linux on the surface.

It’s only a rumor at this point (one that’s been floating around since March this year) but I believe Valve’s ultimate goal is to use Ubuntu as the basis for a new console system, similar to the Xbox, Nintendo Wii and Playstation, one that uses Linux as a transparent foundation where most people aren’t even aware of it’s presence.  Right now the beta testing is to simply get things up and running stable on PC hardware and demonstrate a proof-of-concept to prospective developers who might consider following their footsteps and start developing future titles with Linux in mind.  Once their flagship games have been ported over they may soon after decide to release their very own “Steambox” console, a multimedia systems that will dominate the living room entertainment center as we know it.  It will basically take all the best things about the PlayStation 3 and improve upon it, becoming a console system that isn’t just for gaming but a comprehensive entertainment system with features like access to on-demand video (Hulu, Netflix, etc.), the ability to DVR live television, the ability to browse the web with browsers like Firefox, run thousands of applications for word processing,  video editing, sync with your phone and really anything else the user might want to do; anything that Linux is already capable of or will be capable of in the near future (and it’s already got QUITE a lot to offer right out of the box, all completely for free).

I own a PS3 and a Nintendo Wii.  I barely use the Wii at all (it is, granted, dated hardware) but I have been very pleased and frankly surprised by how relevant my PS3 has remained, considering that the first model hit store shelves 6 years ago and it’s still a thriving platform.  You can watch Netflix on it in HD with surround sound, play Blu-Ray, play videos from your computer over the network, insert USB sticks and access the media on that, browse the web (sorta; the browser is atrocious) and you can purchase some games from their own PlayStation Store online and download them to the system from the comfort of your couch.  The only thing you can’t really do with it is… well, just about anything else.  You couldn’t install, say, Microsoft Word or Open Office, you can’t install Skype, you can’t install a LOT of things, primarily because the operating system that the PS3 runs is closed source and developers would have to spend money and time to create custom ports of their software for it.  The same goes for the Wii.  The next Xbox, however, is very likely going to have Windows 8 on it and will support Windows-based programs being installed on it (probably), but it’s yet to be seen if Windows 8 itself is going to catch on and whether or not people will enjoy using it in the first place; it’s interface borders on being “completely alien” to most users new and old and it has an uncomfortable learning curve.  Then again, it’s yet to be seen what kind of interface might be seen on a Steambox (it certainly wouldn’t have to be the default Unity interface that Ubuntu uses by default, but there’s no reasons it couldn’t be if you wanted it to be and that’s just one of the great things about the idea of a Linux-powered console).

Best of all, Linux is an open-source platform, which doesn’t usually mean much to the average consumer but does mean quite a lot to software developers/programmers.  At this point it feels similar to the speculation that was around with the Android Linux operating system was first released by Google for smartphones a few years back.  Nobody was sure if it was really going to be able to catch up to the innovative iPhone back then.  Yet here we are now, just a few short years later, and the iPhone is now actually being out-sold by Android phones and all the while perhaps 95% of Android users didn’t even know their phone is actually running Linux.

I’ve been hearing more and more stories from clients I have worked for and from other techs who do what I do for a living.  People are getting phone calls from a call center filled with employees that only have East Indian accents (for now) claiming to work for Microsoft/your ISP/some company you’ve never heard of/etc. telling you that your computer is infected with a virus and that they would like to help you remove it… for $130 or so, or whatever they charge your card if you actually give it up to them.

However, it is often a scam that is based upon social engineering.  Social Engineering is a term used to describe the act of manipulating a person into believing you’re not a con-artist, or something like that.  Someone calls you out of the blue telling you that your computer is infected, that they’ve been receiving “signals” or whatever  from your computer that indicate you are infected with a virus.  They tell you they work for someone like Microsoft and their tone of voice is rather urgent and often outright rude.  They’ll tell you to do things to your computer that you likely never do on a regular basis, like press the Windows button + R (which brings up the run menu) and type some command into your computer, all of this in the hopes of convincing you that they are who they claim to be.  I’ve never called a psychic on the phone before… but if they were to call me out of the blue and use their “cold reading” skills to try to trick me into thinking I had a virus on my computer, talked me into putting a virus on my computer and/or simply insist that give them my credit card number to see me through some false peril… well that’s what you’ve got here.

If you get a phone call from anybody claiming to be from “tech support” or Microsoft or any handful of other places/companies, be on your guard.  It’s right along the lines of getting an email “from your bank” asking you to reply with your social security number, account number and passcodes to confirm your identity or something fishy like that.  Better yet, if you are already certain your computer is just fine and have a little experience with the computer, flat out waste their time for your own entertainment (if you have the time to spare).  You don’t even have to be at your computer.  Tell them to “hang on” and put the phone down for a few minutes; make some coffee or a sandwich.  When they’re talking interrupt and say you didn’t understand them, then put the phone down again.  Maybe you have a Macintosh or run Linux; would’t that be ironic.  Use your imagination, or just hang up.  In any case, be aware that there are scam artists out there calling random number trying to find someone who will fall for their manipulations.

Heads up Norton users!  A headline hit the news last night about the confirmed leak of source code for the popular Norton Antivirus software by Symantec.  You can read the articles for yourself here and here.

For those who aren’t tech savvy, the word “source code” refers to the so-to-speak “recipe” for the development/creation of a program.  It is literally the instructions that are more or less written by computer programmers.  This kind of information is proprietary and is often a trade secret, much like the coveted ingredients list for Coca Cola or my moms apple pie.  If one were able to obtain such information, say a competator or the creators of compuer viruses, one might use this information to one-up the software or, more importantly, exploit design flaws to circumvent the software.  In short this means it is quite likely there will be a new breed of viruses on the horizon that will be capable of outsmarting Norton, rendering it useless and crippled.

Symantec has been trying to downplay the severity of this breach by stressing the age of the code, stating that the origin is a version of their software that dates back to 2006, or so we’ve been told thus far.  This is an attempt to defuse the concern by implying that their latest software is far different at its core and that there won’t be very much that is useful to virus writers because they still don’t have their hands on the latest blueprints.  But the reality of the situation is far less peachy than they would like to paint it.  In the world of computer programming software and even entire operating systems will retain a fair chunk of old code from previous versions simply because, well, it’s already been written and if it “works” then there’s little need to rewrite it from scratch.  I’m not saying source code is never rewritten, revised or updated from time to time, but when it comes to large programs such as Norton Antivirus that’s made up of tens of thousands of lines of code it could easily be argued that there is likely a good percentage of old code that has been retained for years without ever being modified.  It would be like having a castle or fortress that is under continuous construction and maintenance.  You can’t afford to tear the whole thing down every year and rebuild it from scratch, so instead what you do is build around and upon the existing structure and make repairs to the parts that need repairing the most.  This means that likely most of the fundamental structure is retained and knowledge of the construction of such a structure could be used by an enemy to find a previously unnoticed vulnerability.

In the interest of full disclosure I will have to admit that Norton hasn’t been on my list of recommended software since the late 90s when it was practically the only anti-virus software available.  It’s early bird status was followed by years of successful marketing and advertising, which lead to its continuous wide spread recognition of the software/brand name, giving the impression to novice computer users that Norton really is the best thing out there.  ”How could it not be good when its so popular?” they might ask themselves.

I am here to tell you that the number one problem I fix for people in this line of work is virus removal and far too often I see systems that are running Norton that have become utterly trashed by multiple viruses while Norton gives inaccurate scan results, claiming the system is clean and virus free.  This is particularly irksome to me because when you consider the wide spread saturation of their software along with the monetary cost to the users for the renewal every year you would have to expect the company to use their position and resources to everyones benefit.  Despite its wide spread usage and price tag it fails to survey new viruses and develop new definitions for capturing and stopping them in an effective manner and so many users never seem to get their moneys worth.  I am willing to give the benefit of the doubt and accept the fact that there is no such thing as a “perfect” antivirus software, but you should expect to be given better treatment and results if you’re paying upwards of $70 a year for protection, especially when there are free alternatives out there that have been statistically shown to do a comparatively better job.  And to think these kinds of problems existed before some of their source code leaked.  Now that some source code has leaked and the potential for new viruses to be developed to exploit Norton itself are likely right around the corner I feel obligated to suggest that people avoid using it all together.  No amount of marketing or PR can change the consensus of most IT professionals who can see past all the BS and to me this incident is more than just one more nail in the coffin.

So what do I recommend instead of Norton?  I mentioned that there is “no such thing as a perfect antivirus” but there are alternatives that hold a higher reputation than Norton that cost a fraction of what Norton costs or even nothing at all.  In past blog entries I’ve mentioned Microsoft Security Essentials, Malwarebytes and Combofix and still recommend them, so here’s a little information about them.

Microsoft Security Essentials is a free antivirus solution that Microsoft itself actually produces and it’s quite popular in the IT community right now for a couple of reasons.  I already mentioned that its free but it is also effective and not as resource intensive as other software.  There’s also a new stand-alone bootable version of it that’s going through public beta testing right now which is handy to have for particularly difficult viruses.  You can read more about it here.  Be aware that there has, in the past, been a rogue malware impostor simply called “Security Essentials 2010/2011/2012″ which people have confused with the real deal, falling victim to a trap.  You can download the real deal from here.

Along side MSE I also recommend users purchase the full copy of Malwarebytes for the one time payment of $25.  Some of the handy features it has is an active connection monitor which will automatically block your computer from attempting to connect to known malicious web servers.  It also features an active process monitor like a traditional antivirus and will help prevent a good number of rogue malware type software from infecting your system.  There is a free version of this available but its active monitoring features are disabled. I’ve been using it in the field for over 2 years now and it has worked incredibly well for helping clean systems that had already become infected.  You can read more about it here and download/purchase it from here.

Finally a tool I use quite often to help clean systems that have already become infected is a program called Combofix, which is free.  This isn’t so much a traditional antivirus that runs in the background as it is a stand-alone utility for scanning a system after it has become infected.  It is regularly updated so it’s best to not bother downloading and using it until you actually have to.  You can read more about it here and download it from here.

In conclusion I strongly advise my clients to not use Norton Antivirus because it’s one of the most over-hyped, over-priced products out there right now and with the news of parts of its source code being leaked it only stands to become an even less effective product that will do less to protect you than other cheaper alternatives out there.

Speaking of alternatives, there is always the option of picking an alternative operating system such as Linux.

Linux is a free open-source OS that comes in many flavors.  We are already seeing Android being adopted by smartphone and tablet users like crazy and it is just one example of a Linux based OS that is taking the world by storm.  But for desktop and laptop users there remains a need for a full fledged desktop OS and there are many out there to choose from.  My personal favorite is Ubuntu Linux which you can check out at ubuntu.com.  It’s not for everyone but I can easily say that it is a very ideal choice for the average user.  Keep an eye out for future posts; I intend to record a new introductory video for Ubuntu 12.04 when it is released this coming April.

Update, March 18 2012:  I wanted to add the names of two more utilities I’ve found to work very well for some specific rootkits.  The names of the two programs are:

• Kaspersky TDSSKiller
• Avast Anti-Rootkit

I don’t write blogs much these days but if there’s one thing I’ve learned about writing blogs the golden rule is to make them useful and valuable to people.  As a sort of philanthropic gesture I am now going to reveal a few tricks I use in the field when repairing systems that have already become infected with viruses or malware.  Perhaps these tips will save you some money during these dark economic times.  I can’t promise that these tips will work for you but for the DIY user who’s not afraid to get their hands dirty, it might prove to be very useful.  So lets get right to it:

Phase 1:  Safe Mode (with networking?)

Almost every version of Windows out there (from Windows 95 all the way up to the most recent Windows 7) have a hidden menu you can access at boot that gives you access to a diagnostic profile called Safe Mode.  Safe Mode is a sort of back door mode into Windows that loads the absolute (or nearly) bare minimum of device drivers and background services.  It’s sort of a bare bones environment that is suitable to start your repair from primarily because most viruses aren’t auto-started by the system in this mode, but it’s not perfect.  More on that in a moment.

To access Safe Mode you need to press the F8 key on your keyboard at a VERY specific time.  Typically when you turn your computer on you’ll see a screen that either has the logo of the manufacture of the PC or perhaps some generic startup relating to your BIOS.  At some point that all goes away, your screen will be black for about 3 seconds, and then Windows will proceed to boot with the little scroll bar loading away.  It’s during (or just before) that 3 second window of blackness that you need to start tapping the F8 key.  If done correctly, you’ll be presented with a menu that looks like this:

You’ll use the arrow keys on your keyboard to move the highlighting selector bar.  Typically I will select Safe Mode With Networking, as this allows me to access the Internet and download utilities as well as give these utilities access to definition updates for itself later.

After you select Safe Mode With Networking and press Enter your screen will be bombarded with a slathering of strange and mysterious words…

Don’t worry, this is normal.  (Note: If instead of this screen above you get another menu asking what version of Windows you want to boot, just press Enter again).

Eventually you will get to the familiar blue colored user login screen and you might see an account called Administrator shown there that you’ve never seen before.  If you do, go ahead and select it to log in as “Administrator”.  Otherwise, select your own user name.

Once you’re logged in you have a few options you can take.  The safest way to get started is to actually bring a copy of your utility software with you on a thumb drive or CD to install it from, instead of downloading via a web browser.  The reason it’s not a good idea to try and download via a web browser is because a lot of viruses tend to wrap themselves around a browser’s EXE file so that when the browser starts, so does the virus.  This could potentially happen with a lot of other software so it’s best to try and resist the temptation to run any programs except for the cleaning utilities we’re about to install.

Phase 2:  Cleaning

There are only three pieces of software I typically use with great success in the field for removing viruses and malware.  They are:

• Malwarebytes
• Combofix
• Microsoft Security Essentials

All of the above are free with the exception of Malwarebytes, which functions with all its features on a 30 day trial when you first install it (note that you will see an error message appear when you tell it to start the trial while in Safe Mode; this is normal and you can ignore the error by clicking the OK button when it appears).  To keep the full version running you have to buy it for the low one-time payment of $25 and I strongly recommend it.  Apart from these three the only other tool I use is Google, which I’ll use to lookup exact phrases found within suspicious malware to see if I can find other people talking about that particular virus somewhere online and hopeful discover what unique thing they did to remove it.  Fair warning:  Your mileage may vary.

I typically start by installing Malwarebytes first (however I have had one experience where I wasn’t able to do this until after I ran Combofix so you might need to flip the order of these two tasks), applying the most recent update for it and then running a full scan, removing all infected objects it finds.  A typical scan can take around a half hour to do.  When it’s finished, you just need to click the “Show Results” button and then make sure the results listed all have check marks next to them and then click “Remove Selected” in the bottom left.  If an object doesn’t have a check mark when you first view the results it means Malwarebytes thinks it could be a false-positive result.  Use your best judgment and google to determine if either the file is malicious and/or if the file is a necessary part that can be removed without grief.  A reboot will likely be required when it is finished.  Be ready to hit F8 again when you do this so you can come back into Safe Mode and continue your work.

One thing I’ll often do while I’m waiting for a Malwarebytes scan to complete is take a look at the MS Config utility and see what items are enabled to auto-start when you boot into the system.  To access this, click Start, then click Run (or just click into the search box if you’re using Windows 7) and type in “msconfig” without the quotes into the box and click OK.  Then click the Startup tab at the top.

In this startup list are programs that are told to run right away when you first log into your system.  Almost all of these items are non-essential and to be on the safest side you could probably get away with unchecking all of these items, but that’s usually overkill and might rob you of some convenient feature you’d like to have.  Look carefully down the list for items that have empty path names, or very bizarre characters in their name… I have to admit that at this point experience with this stuff comes in to play.  If you don’t know what something is you could look it up by name with google on a separate computer before deciding to uncheck it  Alternatively, you could use the uncheck-all-the-things strategy and then go back later to add check marks back into the few items you know you need enabled.  You can also check out the Services tab which is to the left of the Startup tab, check the box that says “Hide all Microsoft items” and then use the same judgment to decide if there are third-party services running in the background that don’t need to be.  Google is your friend here for helping to determine if a service is useful or not.

Another thing I’ll do while waiting for a scan to complete is open the Add/Remove Program (Programs & Features) applet from the Control Panel to view all the software that’s been installed on the system.  I target toolbars of any kind first, next by software that is unfamiliar to the user.  Again, google is a useful reference here because you don’t want to remove something that’s known to not be malicious.

The next step is to run Combofix which you can find a tutorial about by clicking here.  It is pretty strait forward:  double-click on the combofix.exe file that you downloaded and follow the on screen instructions.  It’s own scan will also take about 30 minutes or so but it is very sensitive so once you kick it off, don’t touch the computer until its finished.   There is almost no interaction required with the software and it will automatically remove anything malicious it finds, producing a log with a lot of interesting jargon at the end that you can forward on to an expert for further analysis if you’d like.

After all this I’ll typically reboot the system and let it boot normally and then install Microsoft Security Essentials, running a full scan with it right after and checking to make sure the trial mode has been enabled on Malwarebytes.

If all of the above didn’t work, something I’ll try next is to reboot back into safe mode and use the control panel to create a new user account, then log off and log back in under that new account and repeat all the same steps above.  The reason this might help is because viruses tend to damage registry entries for accounts that existed when it found and infected the system.  Because we’re creating a new account in an environment that hopefully didn’t auto-launch the virus, we can then create a fresh account with it’s own default settings and preferences that hopefully won’t be manipulated by the virus.  This kind of problem could also be reversed using the System Restore utility but I’ve found that a lot of times (not always) I try to use this utility none of the restore points are any good.  I wouldn’t be surprised if previous restore points are destroyed by certain viruses making it even more difficult to undo the damage done.  In situations like that I’ve occasionally just created a new user account and migrated all the important user data (documents, etc.) from the old account to the new account, deleting the old one in the end because it’s irreversibly broken.

One last tip I’ve run across in a training video for a competitor of mine who will remain unnamed is to shut the system off by force instead of doing a soft reboot during this cleaning process.  In other words, hold the power button down for 5 seconds and then turn the computer back on after 20 seconds.  The reasoning behind this is that there are a few viruses out there that alter the shutdown script of events that take place during an ordinary shutdown and one of the events it injects into the script is to reinstall the virus during shutdown from a rogue location, as a Plan B so even if the live version of the virus is caught and removed it might be able to recreate the file from an encrypted copy of itself elsewhere.  If you decide to do this my only advice would be to backup the entire hard drive before doing so.  It’s technically dangerous… but probably not THAT dangerous… it’s best to remain on the safe side and not use shortcuts.

Finally a word about a couple of common viruses in particular I’ve run into in the last year:

A few of these viruses going around exhibit the symptom of making all your files and shortcut icons on the desktop vanish.  This is often done with a combination of changing the file attributes to enable the hidden flag, or by moving the files to a hidden location.  It is sometimes also conjoined with malware that tries to frighten you into thinking your hard drive is on the verge of failure, or at the least, claims to be antivirus software itself.  The goal of all such attempts is to get you to give up your credit card number.  Please don’t.

I’ve had great success removing the virus that causes these files to go missing but after it’s been removed it’s not always so easy to reverse the damage and restore the missing icons.  Fortunately there is one program out there that, for the most part, has been able to do this for me very simply and it’s simply called “Unhide”.  Use this program after going through all the above steps to be sure you’ve removed traces of the virus and hopefully it will get all of your stuff back for you.  You can download Unhide from here.

One other common symptom I’ve seen certain viruses exhibit is hijacking certain registry entries to alter file associations, specifically one which makes your computer forget what to run EXE files with, asking instead what program you’d like to open another program with.  I have found that in Windows 7 one trick of working around this is to right-click on a program shortcut and then click Run as Administrator.  This uses a separate registry association which hopefully has not been affected by the virus.  Using this Right-Click>Run as Administrator trick you should be able to run your scanning utilities like Malwarebytes and Combofix from within Safe Mode.

Phase 3: Prevention

Now that we know how much of a pain these kinds of viruses can cause we should talk a little about where they come from and the different ways they can end up on your computer.  I wrote a much longer blog about this topic which you can read here.  Basically it boils down to this:

• Make sure you install all available software updates for Windows itself as well as 3rd party software and plugins like Adobe Flash, Acrobat and Java (among others).  Updates are your friend and help to patch recently discovered security vulnerabilities.
• Pay attention to links people send you in emails.  It’s quite possible their email account has had its password stolen and is being used by a robot to send spam email with links to malicious websites out to everyone in their address book.  Warn your friends if you suspect their account has been compromised and suggest they change their email accounts password before following the steps above to attempt to remove a potential infection.
• Use good anti-virus software.  As recommended above, I prefer MSE and Malwarebytes.  Combofix is only to be used as an emergency utility; it doesn’t have a real-time monitoring feature.
• Consider using a software firewall to block unwanted inbound traffic and unexpected outbound traffic.  Zone Alarm Free is an excellent choice for this.
• Use an ad-blocking plugin to further reduce the chances of a virus sneaking in through a flash-based advertisement.  Ad-Block for Firefox is a great option.  You can also get it for Google Chrome from here.
• Along with these plugins, consider using a better browser.  Mozilla Firefox and Google Chrome have both become superior to Internet Explorer, especially in terms of security.
• Avoid installing “toolbars” for your browser.  If you install one by accident, disable it in your browser or better yet uninstall it via your control panel.
• Avoid using P2P file-sharing software like Frostwire or MP3Rocket.  These methods of file sharing do not have any form of user moderation and anybody can wrap a virus inside a file then name it something innocent/sensational looking to trick people into downloading it and installing a virus.
• Consider adding a parental filter to your computer; you don’t need kids for this.  Having a web filter like K9 Web Protection can be helpful to block your computer from accidentally trying to connect with a known malicious server.
• Lastly, though this is too extreme for most people:  Consider switching to Linux on your desktop.  Linux is free, open-source and is even more secure than MacOS.  Seriously.

I hope this advice has been helpful.  Please leave comments or suggestions about other tips and tricks you use to help remove malicious software in the comments section below!

I recently bumped into someone who is a big fan of Skype and uses it to save money at his businesses, as land-lines cost far more for businesses than they do residential customers. He’s seen real savings by using it and was wanting to migrate his company completely away from the local telephone services and go 100% Skype. One of the hitches here was the necessity to have a fax line that you could send and receive faxes on.

Unfortunately there is no good way to send a fax from your computer using Skype. The audio compression that takes place when sound is transmitted from one side to the other undergoes a great deal of detail loss, and this results in error correction protocols taking over and throttling the speed of the fax modem down to a crawl. So in theory, you could use Skype somehow to send a fax but it would literally take forever.

Enter in online faxing services. These are companies that allow you to send and receive faxes over the Internet. In doing some research to find one that performed well and at a modest price I stumbled across someone recommending a company called PamFax.  It was not long after first trying their service that I was pretty sure I could close the book on this egg hunt.

PamFax is delivered to you as a small program you install on your system and use to create your account.  They offer a free membership program which allows you to send three pages for free to see if you like their product or not.  I decided to sign up for the free account and then used a nearby fax machine where I work to send a fax to my new PamFax number.  The instant the fax was sent my PamFax account page auto-updated itself to tell me I had received a new fax.  Faxes are put into an inbox, just like emails, and each fax is downloadable in PDF format.

Sending a fax is also very easy.  You can either use the PamFax program to upload files you want to send or use the virtual PamFax printer device to send your documents to PamFax when you press Print in any application.  Here’s a video that demonstrates how easy it is to send a Fax:

Of course there will be times when you need to fax a physical document that’s already on paper.  The best way to do that is use a flatbed scanner to scan the documents into a PDF file.  You can do this very quickly with any number of Scanner-to-PDF style programs and any scanner.  A free one I’ve found to work well is aptly called Scan to PDF by Ironfist Software.  It is a free utility that you can use to scan multiple pages and then save all of them as one PDF file, which you’d then upload to PamFax for faxing to one or multiple recipients.

The cost for sending a fax varies based on whether or not you want to pay a monthly fee.  If you don’t pay a monthly fee it will cost you 13 cents per page sent and you will not be able to receive faxes.  If you step it up to the “Basic” package you will be able to receive unlimited faxes at a monthly rate of $5.84 plus 13 cents per page sent.  The professional package costs $8.80 a month, includes 20 free page out per month (9 cents per page after that), allows you to keep your received faxes online forever, and gives you the ability to administrate employee access to the account and regulate their limitations.  So there’s something for everybody.

In the end I was pretty impressed with how easy it was to install and use PamFax.  What’s even more impressive to me is their support for Linux. It’s rare that I have to send a fax but the next time I need to I know exactly what I’m going to use.  Good bye Kinko’s!

I have encountered a good variety of computer problems this year, many of them classic textbook cases. Dead DVD burners that needed to be replaced; computers running slowly because they really needed a RAM upgrade; hard drives needing to be replaced with larger ones; networks with printers needing to be setup so multiple computers can send jobs to it…. these are the kinds of problems that we were taught how to resolve in school, primarily because they  were easy to recreate/simulate for lab assignments.  I remember the fun we had when students were split into pairs and told to “test” each other by breaking a system and not telling the other person HOW they broke it, as a challenge to see if they catch all the hidden problems.  Wanna make a computer run slow?  Pull a stick of RAM out of it, slightly.  Wanna make a network printer stop working?  Change its IP address.  Wanna stump someone with no video on the monitor?  Just turn the contrast/brightness all the way down to see if they can figure it out.  The goal was to reinforce the premises that you should never, ever dismiss the lowest common denominator when trying to think of different  diagnostics and best case solutions for a problem.  Even something as simple as “is it plugged in?” should never be assumed to have been checked until you’ve done it yourself.  In networking, you would say “start with the physical layer, and work your way up to the higher levels until you actually reach the application.”

These problems don’t strike me as novel or very interesting, mostly because you expect to see them occur at SOME point in time and at random.  Electronics wear out, lightning can strike at any moment, dust buildup shorts something out or jams a cooling fan; these things just happen from time to time.  But there was one issue I saw this year that really stood out as occurring more frequently than any other problem by far.  A problem  that seemed to happen so suddenly, so widely that you could almost call it “trend setting”.  So I wanted to take a look back and talk a bit about a problem I’ve seen more often than anything else this year:

“Warning:  You’re infected!  Click here now!”

The most prominent problem I saw this year, more than any other problem I got calls about, were from people saying they had gotten alerts popping up on their system similar to the one pictured above.  Typically you would be intimidated by a popup that said your system had a LOT of viruses on it and to click on various buttons/links to remove them.  Unfortunately it was all a ruse as these alerts were themselves part of a virus masquerading around as anti-virus software, taking computers hostage.   Their names and appearance had some variation but most of their tactics were the same:

• Prevent user from opening any other applications (including Task Manager)
• If you were able to open a web browser, any page you tried to visit would be replaced with a page that would fear-monger the user even further
• Change the browser proxy settings to point to a non-existent server and in doing so prevent the user from accessing the Internet for downloading removal tools
• Annoy the user with never-ending, obnoxious pop-ups that would invite the user to pay the developers of the fake anti-virus software ransom money
• Replicate itself across multiple, random locations on the hard drive, making it more difficult to remove manually

I began to get a lot of phone calls for this exact type of issue during the middle of the summer this year, and of course everyone wanted to know how their computer came to get this sort of junk software on their machine in the first place.  Along those lines:  Where do viruses come from, how could one have gotten on my computer and WHY on earth would someone create such an evil thing in the first place?

I don’t have the monetary resources to conduct an “official” study (and as such you should classify everything here to be anecdotal), so the next best thing I can do is look for things that were in common between PCs that fell victim to the same infection at about the same time.  The one thing that stood out the most to me was that Adobe Flash, Adobe Acrobat and/or Java were out of date and needed updates to be installed.

In the year 2010, Adobe has had to make multiple announcements about zero-day exploits found in their Flash plugin that could allow Flash to do things like crash a computer or to take control of it (e.g., facilitate the installation of a malicious payload or virus).

Just what is Flash, anyway?  Flash is a plugin for web browsers that has been a mainstay in webpages for over a decade.  Youtube videos, for example, are played within Flash.  Most advertisements you see on the web use Flash to animate video, elements, buttons, letters, etc.  Some websites are made entirely in Flash.  In the early days Flash was designed as an alternative to animated gif images and cartoon-like animations because for some uses it could actually conserve bandwidth because instead of pixels and color pallets taking up file space, you would instead be working with vectors (think connect-the-dots to create a shape of something, like a stick-figure man, and move the dots/vertices to animate it).  An awesome example of cartoon flash animation using very little bandwidth is www.homestarrunner.com (a favorite cartoon series I used to follow in the old days).  Over time Flash has evolved into quite a feature rich plugin that many have attempted to clone and dethrone, but all attempts have failed (so far).

In any case, as a result of being more efficient than animated bitmaps and saving web hosts money on bandwidth and faster loading times while increasing the “eye-candy factor” during the days of dial-up, Flash became a preferred/common means of deploying advertisements on the web, and eventually advertising itself became so big that there are now companies that do nothing but produce and host Flash-based advertisements for other websites. What this means is that many websites do not actually host/serve the advertisements that you see on their website, as they have offset the bandwidth requirements for this function to third party companies.  Unfortunately, because advertising is a big deal online, it raises the bounty and incentive a malicious hacker might have to penetrate the advertising servers and replace clean advertisements with infected versions that would download and install Malware all by itself, taking advantage of security exploits in the plugin that have not been patched by the user.  This has been going on for at least the last 4 years or more and it’s a phenomenon knows as “Malvertising”.

So what are some ways to prevent this type of thing from affecting you?

1. Make sure you apply updates for all software on your computer when presented with the opportunity

If you see an alert like the one pictured above, address it immediately.  Far too often I see users just minimize the window or click “Later” and forget about it for the rest of the session.  The same thing goes for Windows updates, Adobe updates and generally speaking any updates for software that you use on a regular basis.  Updates happen because security vulnerabilities are found and patched, or slight tweaks resulted in an increase of the programs performance, or because they are adding a new cool feature.  Whatever the case may be, software updates are your friend and you should welcome them without hesitation.  If you are asked to update a piece of software you have never heard of before,  just type the name of that software into Google.  With just 30 seconds of reading you should be able to determine if the program that has an update pending is legit or malicious.

2.  Use Anti-Virus software that is backed by a good reputation, not just hype and marketing

The two most common anti-virus programs I’ve encountered  on computers THAT WERE ALREADY INFECTED has either been Norton or McAfee; both have never seemed to live up to their hype or justify the sponsorship of PC manufactures and Internet Service Providers.  Norton in particular spends gobs of money on absurd advertisements about how you should protect your oscillating fan from David Hasselhoff or saving your unicorn from Dolf Lundgren.  The use of silly metaphors in them are meant to parody the fact that most people don’t understand viruses anymore than they understand Dolf scorching My Little Pony with a flame thrower, purely for illustrative purposes of course.  Lets dumb it down so much that people will say, “This is so dumb, it’s smart (advertising).”  Now we know why a copy of their software costs around $60 or $70 per year…

The sad truth about anti-virus software is that NONE OF THEM are perfect or necessarily worth their weight in dollars, simply because virus programmers have the upper hand.  If a hacker discovers a vulnerability that no one else has discovered yet, he may just keep it in his “stash” for use later.  OR, he might sell that knowledge to the Russian mafia or any number of other interested parties who have their own stash and secret agendas.  It is suspected the Stuxnet worm that ran rampant through Iran earlier this year was the product of a government agency, due to the sheer amount of zero-day exploits it contained for propagating itself, along with its overall sophistication and extremely specific targeting.

Was it a coincidence that days after Adobe announced the discovery of a zero-day exploit in their Flash and Acrobat Reader software in early June that a lot of people started to call me for the exact same Malware problem?  It’s quite likely the vandalism on advertising servers was timed to correspond with these vulnerabilities to maximize exposure.  It takes Adobe around 2 weeks to release patches for vulnerabilities like this so there is a window of time users are exposed and at risk, and this window of time extends out further if you avoid applying updates.

Despite this sad and depressing fact, you’ll be happy to know that many anti-virus programs do provide generous protections that you cannot otherwise get without them.  There are two programs I recommend everyone check out:

• Microsoft Security Essentials
• Malwarebytes

Microsoft Security Essentials is produced by Microsoft itself and is a free program you can install on your system.  It will actively monitor your computers activity and help prevent virus infection.  I encounter network security professionals in web forums here and there and most of them have really begun to sing praise for this program, because of it’s small footprint and high level of virus detection and removal.  Malwarebytes is another program that comes in a free form (though there is a paid version that automates all of it’s functions so you don’t have to do manual scans and updates with it).  Malwarebytes has been an absolute life saver for me this year as it was able to effectively cure about 8 out of 10 PCs of all their woes with one scan.

There are many other commercial (pay) anti-virus programs out there that are good, such as AVG, Avira Anti-Virus, Avast, etc., but I don’t have the time or resources to review all that are available.  While you might be able to find other websites out there that post “comprehensive reviews” of this type of software, it should not surprise you that sometimes these articles are just advertisements for commercial anti-virus software dressed up to look legit and non-partisan.  In my opinion, the best reviews for these things come from individual users and a great place to find reviews for antivirus software is Amazon.com.  They sell some anti-virus software and each of them have their own collection of user reviews that are worth reading over if you decide you want spend money on extra protection not offered by free solutions.

3.  Install A Software Firewall Solution

If your computer is directly connected to the Internet (and does not pass through a router of any kind) then you are putting your computer on the front line and you should protect it with some armor if you want to stand a chance in the wild jungle that is the Internet.  Firewalls prevent unwanted network traffic from passing between your computer and the Internet.  In the same way Flash has it’s own flaws and vulnerabilities from time to time, so too does Windows itself and many vulnerabilities can be exploited with nothing more than a network connection.  Having a firewall in place helps eliminate this possibility.  A firewall can also prevent rogue software that is already on your system from “phoning home, contacting the mother ship” to update itself or otherwise expose your personal data to would be data thieves..  It’s not anti-virus software, but it does add a critical layer of protection.  Windows itself comes with a firewall built in but it’s not as feature rich as some third-party applications out there.  The most popular free firewall that I know of Zone Alarm Free.

4.  Use a proper Ad Blocking browser extension

One of the great features of Zone Alarm Free is the ability to let it block advertisements for you, although its not very smart about it as it basically blocks all gifs or flash content embedded in a website.  This can break a lot of websites that have legit uses for Flash, like Youtube.  So you may want to look into a more proper ad-blocking plugin/add-on/extension for your browser.  A great one for Firefox is called Adblock Plus.

5.  Use a safe web browser

Recently I stumbled across a funny description of Internet Explorer:  “It’s a great tool for downloading Firefox or Google Chrome.”  And it’s the truth.  Internet Explorer has struggled to achieve a respectable reputation among security experts as being a secure browser, when compared to others that compete against it.  Among them are:

• Mozilla Firefox
• Google Chrome
• Opera

These are all very capable browsers that have a great reputation for handling security and also have shown impressive turnaround when vulnerabilities are discovered.  I would highly recommend you download and install one of the above browsers and start to use it instead of Internet Explorer.

6.  Avoid And Uninstall Web Browser “Toolbars”

The above image is an exaggeration of a point I would like to drill home:  Toolbars are 99% junk and often facilitate no additional functionality than a web browser already has built into itself.  Pop-up blocking and search bars are standard in all modern web browsers, for example.  Many times I have seen toolbars for “MyWebSearch” on computers that happened to be infected with a virus.  I can’t necessarily say there is a causal connection between that particular toolbar and an increase in exposure to malicious software, but its fair to suspect it because if you search for “mywebsearch” on google, every single link (except the first one) goes to instructions for how to remove it.  It’s clear that NOBODY wants this toolbar, and the same could easily be said for most toolbars.  Get rid of them, please!

The easiest way to remove most of these is to use the Add/Remove Software applet in your control panel (In Windows Vista/7, it’s called “Programs and Features”).  If this fails to work then you can often find instructions for manual removal by searching for them with Google.

7.  Avoid P2P Filesharing Programs

Limewire is dead, but the way it worked will live on in other programs like it.  The way Limewire worked mostly relied on you connecting to other peers like yourself and the mesh collective would commence to pass files back and forth in a decentralized fashion.  The problem for Limewire is that it wasn’t entirely decentralized, which is why they were able to shut it down like they did Napster several years ago.  But still, the primary way it worked was by letting anybody share pretty much ANYTHING they wanted, without any real fear if they did something like disguise a virus as a popular new song by some teen-pop musician and share it out to the world as a “joke.”  Using software like this is your call and any legal considerations involved weighs entirely on you.  If you do decide to use file sharing software of this nature, make sure you police all your downloads to be sure you haven’t downloaded a Trojan horse.

8.  Consider Adding Parental Controls To Your PC

Not everybody reading this (in fact, few people reading this) would be willing to walk forward and admit to visiting porn websites online, but such websites make up a large chunk of the web and due to the rogue nature of some of them you are more likely to find ads, script code laced with viruses or strait up automatic downloads for executable binaries with names like “Video.exe” that can lead to your computer being infected.  It’s quite plausible that you might even visit one of these sites “TOTALLY BY ACCIDENT!!!”  So one thing you might consider using is a parental control blocking application that filters out web addresses and reduces the chance of you visiting one by accident or otherwise.  A robust, free parental control program worth trying is K9 Web Protection.

9. Consider Using Linux For Internet Stuff

It would be hard for me to write all of the above out without making a passing mention of using a different operating system, at least part of the time.  I realize not many users are interested in making a big switch from one OS to another, but it is very easy to at least get your feet wet with a Live CD.  In the case of Ubuntu Linux you can boot the entire OS from a CD without making any changes to your computer.  It’s like playing a demo for a video game before deciding to install the full copy, for free.  Instructions for downloading, burning and booting are right on Ubuntu’s website so if you’re even SLIGHTLY tech savvy you may find you enjoy working in Ubuntu more than you do Windows and feel relief from not having to worry about viruses or malware infecting your system.

Conclusion

As I mentioned before, this Malvertising problem is not new but the spike in its frequency of occurrence this year was interesting to me.  It wouldn’t be far out to predict another wave of infections like this striking again, but with the above advice and your increased awareness of the possibility of being infected in such a way should help to drastically reduce the chances of you falling victim to something like this.

Preamble:   The techniques described in this guide are intended for educational purposes and should not be used to bypass copyright restrictions or download copyrighted material without consent from the respective owners/licensees.  In the below example I use a track by Nine Inch Nails for this demonstration for two reasons:

1.  I already own this album (in fact I own every Nine Inch Nails album; I’m what you would call a “loyal fan“).
2.  The album was published under the Creative Commons Attribution Non-Commercial Share Alike license.  This means I could give you a copy of the song because I purchased it.  Look out for musicians who publish their works under licenses like this.

So let’s get to using this Youtube Downloader thingy!

First, download the software from Download.com by clicking here.

Run/Open the file once you have downloaded it to install the software.  Once installed, you’ll have a new shortcut in your Start Menu.  This is what the program looks like when it’s running:

Leave this window up and go visit Youtube.  Find a video you like and then copy the URL from the address bar at the top…..

…into the first box in Youtube Downloader, like this:

Now click Download.

Once the video is downloaded you can convert it to an MP3 by changing the selector at the top from “Download a video…” to “Convert or play a video…”, like this:

Now all you have to do is click the Browse button to search for the file you just downloaded, and change the “Convert Video to:” box to read MP3, like this:

Now click Convert.  It will ask you about quality settings (and of course it’s best to just leave it on “Best Quality” and click okay).  That’s pretty much it.  A conversion process will happen, taking perhaps 30 seconds,  and you’ll be given an MP3 file that you can play on pretty much any portable audio player out there.  It’s up to you if you want to delete the original video file.

A word about piracy/file-sharing

Piracy/file-sharing can be a very polarizing topic to talk about, especially when the conversation occurs between professional musicians who make their living off writing music.  On one side of the fence you’ve got your Lars Ulrich and Gene Simmons who see piracy of their music as a direct threat to music sales and thus their paycheck.  On the other side of the fence you have bands like Radiohead and musicians like Trent Reznor who see the sharing of their music as a marketing platform that can increase band exposure, increase their fan base, and subsequently increase their physical merchandise and ticket sales.  Both sides are entitled to their opinions but I lean towards the latter group when thinking about this stuff.

Along the lines of music piracy is software piracy.  There is a software developer who goes by the name Notch who created a computer game called Minecraft by himself that has earned him nearly one million dollars in under a year, and it was still in the Alpha stage when it hit that impressive number.  He has a very keen insight into piracy and I would like to suggest you check out his blog post about the topic if you have the time.  It mostly boils down to distinguishing (or debating) the difference between the loss of potential revenue versus actual revenue lost, determining a fair way to measure the differences.

In marketing there is a strategy known as “loss-leader” and pirated music could be thought of as a loss-leader for a musician who has additional products to offer, like vinyl, or limited “deluxe edition” packages, not to mention concert tickets and who knows what else (one of my favorite musicians offers up everything from autographed cover art by Strom Thorgenson to 5 hour long studio workshops with the band and their very own equipment).  Then there’s new, up-and-coming musicians who don’t yet have anything better to hope for than a chance to be listened to and are willing to let people preview their entire collection in the hopes of turning them into a loyal fan who will go buy all their albums and other merchandise someday down the road.

Shameless plug: Check out my Kompoz profile to listen/download/pirate my music.

So about 90 seconds ago I learned about this website and knew I had to write a quick blog about it.  The site is called Ninite Easy PC Setup.  This is a website that allows you to download multiple popular Windows applications, from web browsers to anti-virus software, and install them all at once!!  This is a HUGE, HUGE time saver.

You look through their selection of software, check off the programs you want and it will create a custom bundle from your selection and wrap it all into one easy install package for you to download.  When you run the installer, it installs all the apps, one by one, automatically without user intervention and without any spam “extras” that might come along with some of them (like browser toolbars that do more harm than good).

I was just browsing Ubuntu Forums recently and someone wanted to get a second opinion to see if it were indeed true that Linux doesn’t need anti-virus software.  I humbly obliged them with my own answer on the matter:

You don’t need anti-virus for Linux. Others in here will do a better job at explaining why this is, but in short, the OS has a big advantage here due to it being open source. The operating system is a product of crowd-sourcing, much in the same way as Wikipedia has been since it first showed up several years ago. And much like the highly-moderated articles of Wikipedia that require membership and an approval process for changes made to locked articles, so to is a strict moderation that goes on with the source code for Linux before it’s allowed to become part of the official distribution. Everybody is out to identify possible flaws or weaknesses or bugs in the source code and it’s much easier for any single person to make a contribution because the OS and much of the software that runs on it is open-source.

In Windows, the users don’t have the luxury of being able to dig through the source code to look for flaws. All they can do is report symptoms of problems to Microsoft, and the limited number of paid programmers that do have access to the source code then have to decide what flaws are the most important and which ones don’t merit their attention. So with Windows, a bug that affects only 500 people won’t be as important as a bug that affects 500,000 and probably won’t be fixed at all. But if it were Linux and if just one or two of those 500 people were a programmer who had access to the source code and figured out how to fix the problem on their own, the other 498 would actually stand to benefit from a patch that ends up being released thanks to the work of that one developer who had some spare time on his hands and decided to do something about a bug simply because he could.

So throughout the long life of Linux there has been this much more diversified, seasoned, multi-cultured source for development feedback that has helped to make it a much stronger, more “mature” operating system, especially in terms of the way security was designed. If there was ever a person out there who found a way to circumvent that security, there is at least one other who knows exactly how to repair the flaw. The reason viruses are able to best Windows is because their developers can only patch so many holes, and the ones they don’t have time to get around to end up being exploited the most. Third-party software developers that make Anti-Virus software make a killing because Microsoft is unable to handle this responsibility all by themselves, and even still, the best anti-virus software isn’t perfect.

The reason anti-virus software isn’t necessary in Linux is simply because the OS and its updates that patch vulnerabilities do the exact job anti-virus software in Windows is meant for: Prevent unwanted, malicious software or network activity from compromising the system. If there were a flaw in Linux found that allowed something like that, it wouldn’t be the job of some third-party software to safeguard the user against but the job of the OS itself. The reason anti-virus software even exists is simply because Microsoft is unable to handle the immense work load of patching their own source code as well as a crowd of Linux geeks can.

Am I saying Linux is perfect and invincible to viruses? Might it become more susceptible to viruses in the future if it were to ever become as popular as Windows is today? I would think that with an increase in the number of users would also come a complimentary increase in the number of clever developers that would only help to increase the number of eyes available to find flaws and fix them. Saying that Linux would get a lot of viruses down the road because more people are going to use it is like saying Wikipedia will become rife with widespread, uncontrollable vandalism because more people visit it. It hasn’t happened yet, and very likely never will happen because of the way it is designed, moderated and improved upon by the hive mind.

EDIT to add: As mentioned in the first comments below, I failed to acknowledge that while Linux is more robust in the area of security, nothing can compensate for the weakest link in this arrangement:  The User.  A novice user could easily be enticed by a sinister website  that tells them to download a deb file which might contain malicious code and absentmindedly install it or execute a destructive command from the terminal window because they didn’t know any better (like rm -rf ~/*).  Fortunately for novice users there is little if any need to actually venture out into uncharted territory like a terminal window or strange websites to get software, thanks to the official repositories that contain a HUGE collection of software which continues to grow.  I’ve even heard you will soon be able to purchase proprietary Linux-based software through it.  Unfortunately, little can really be done to compensate for user negligence, and trying to compensate for all possibilities would likely result in too many annoying alerts and prompts for the average user (like when Windows Vista sprang the UAC on its users).

There are only a couple of circumstances that I believe anti-virus software on a Linux platform would might be worth having which involve helping to protect other Windows systems.  Say you got an email from someone that contained a virus but you never knew it was there and forwarded it onto someone else who uses Windows, resulting in their day being ruined and you being blamed.  So that’s one scenario.  You might also have a Linux server administrating a network of Windows based workstations which you have read/write access to and use the server to conduct scans of these machines over the network, but at the expense of finite network bandwidth and CPU cycles on the server.
