At PCMD, we perform all types of computer repair, but roughly 80 percent of the work orders we write involve infected systems that require virus removal, protection, and education for the clients on how to reduce their online risk.   Here is a sample of the questions asked most frequently in the shop.

What is a computer virus and how do I know if my system is infected?

The term “virus” is commonly used to define a huge variety of computer files that are designed specifically to confuse the operating system, steal identity information, and just to create general havoc on the internet.  Sometimes when a user gets infected, the effects are immediate…can’t open programs, can’t load web pages, and other easily recognizable symptoms.  Sometimes, however, the changes are slow to develop, and the user puts up with the annoyance until it’s too late.  An unchecked infection can corrupt your operating system, destroy data, and basically turn your machine into a paperweight.

How did this happen and what can I do to prevent it from happening again?

Most people get “caught” by a bug picked up on the internet.  The highest risk areas online are adult entertainment, shared music files, and social networking sites.  Anything on the internet that says it’s “FREE” should be regarded as high risk.  There are things the user can do to increase his/her protection:  First, use a high-quality bundle of security software on a regular basis.   Second, do not install a new anti-virus product without completely uninstalling the old one.  Practice safe net-surfing.  If something comes to your screen that you have ANY hesitation about, close it immediately.  Be mindful of unsolicited emails.

I pay for anti-virus software, why didn’t it work?

The desire for a flawless anti-virus software is unattainable.  Every day, thousands of new and mutated infections are unleashed onto the net.  Even the most sophisticated products can’t keep up with the influx.  In our experience, the pay-for-use versions are typically older, less sophisticated programs and tend to have an effectiveness rating in the low 20’s (on a scale of 100).  We use a free-for-personal use product called “Avira.”  Avira has a capture rating in the low 80’s.  What do those numbers mean for the user?  It means the user takes responsibility for the balance of their security.

Can I fix this myself?

You can try.   Isolating and removing infected files is a tricky and time-consuming process.  Most computers need to be on our bench for 4-6 hours before the process can be properly completed.  If you are not extremely savvy with software technology, I recommend you have a professional perform the procedures.

Finally, we now live in a world where it is vital to stay connected.   That connection, however, is perilous.  If you have any questions or comments, please feel free to email them and we’ll respond as quickly as possible.
