How to Avoid Computer Viruses – Part 2

The One Way to Get a Computer Virus

There is only one way your computer can get a virus: by running a bad program.  It’s not browsing websites or opening email attachments that will give you the virus, but doing these things can launch that bad program behind your back. The following list describes how you can start avoiding computer viruses and keep your data information safe.

4 Techniques to Avoid Computer Viruses:

1. Read links – The best way to avoid computer viruses is to keep them from getting on your computer in the first place.  Hover over a link before you click on it and see where you are going.  See Part 1 in this series for more information on this crucial first step of virus protection.

The same applies for popup warnings on websites.  If you don’t know what the message means, or aren’t expecting it, don’t click “Yes.”

2. Good Virus Protection Software – You need good antivirus software on your computer.  This is essential.  We recommend Kaspersky Antivirus: we install it on our clients’ computers because of its effectiveness and minimal impact on performance.  In our experience, Norton and Symantec products have a negative impact on performance and we do not recommend them.  See the AV Comparatives website for a comparison of many AV products out there.

You should also have good anti malware software.  While many traditional AV programs offer anti malware features, most are not as good as MalwareBytes, the product we currently use.  You would think AV software would catch it all, but it doesn’t appear to work out that way.

We also offer our clients a third layer of protection, which is filtering website traffic before it comes into the network, thereby blocking known bad pages.

3. Keep everything up to date – Virus writers look for known security holes and exploit them.  The easiest way to prevent this is not to have security holes.  Do this by keeping all of your software up to date, especially Windows, Adobe Flash player, Java, and all of your web browsers.

Having said that, remember that sometimes having the latest and greatest introduces incompatibilities.  Internet Explorer fixes security problems with new releases, but also breaks certain websites, so this is a balancing act.

4. Beware email attachments – While it is possible to get infected from a virus merely by receiving a bad email, these are exceedingly rare.  Far more common is receiving an infected attachment and opening it.  First of all, all of your email should be filtered by at least one spam filtering service.  Second of all, don’t open any attachment you aren’t expecting.

If someone sends you something out of the blue that doesn’t make sense, that you didn’t ask for, or that’s out of character, don’t open it.  Reply back and ask if it’s legitimate.  If they say it is, and you know the person, then go ahead and open it.  If not, they’ll probably appreciate that you just let them know they are infected.  Then send them this article so they can be as clean and well informed as you are!
