Often times you don’t think about what might be lurking on your computer until your hard drive is about to crash, web pages load at a crawl, or the blue screen of death pops up.  When those things happen, it’s a sign that your computer is sick with malware and needs some TLC in the form of antivirus software.

Why you need it

All that clicking can lead to some bad stuff installing itself on your machine.  Things like Trojan horses, viruses, worms, and spyware are created with the sole intent of damaging your computer.

How it works

Antivirus software runs in the background, constantly searching for all the bad stuff that may be living on your machine trying to make it sick with junk.  It finds the junk and the associated antidote to get rid of it for good.

Where do I get it?

Antivirus software can be downloaded online and for free from trusted computer security companies like AVG.  While free versions may not have all the bells and whistles, they serve as a first line of defense.  If you elect to purchase antivirus software, be aware that the licenses expire.  Fortunately email reminders pester you to keep your antivirus software up to date.  Purchasing a multi-year license ensures that your current license stays active longer so it can continue to protect your PC while you put your mind at ease.
