A few months ago, I got a new (to me) computer. I was just messing around with it on the internet (without any antivirus program), and got hit. Suddenly, a little box popped up, telling me that Spyware was detected, and Windows would download the latest program to eliminate it, and another box would (continually) pop up saying that it was downloading AntiVirusPro2009. I hadn't heard of it before, but was suspicious of it, and stopped it and disconnected (on good old fashioned dial up). I then got BitDefender, which apparently got rid of it (I shortly thereafter ditched the BitDefender, which had several irritating glitches....not least of which was the fact that it slowed my computer to an excruciating crawl). I now have the trial version of NOD32 on two of my computers (getting rid of the even slower Norton on one computer), and it seems to run great. Fast and so far no problems. I just downloaded the full yearly version, but have yet to install it. Anyway, my question: Just what does an infection like AntiVirusPro do (other than irritate the crap out of you)?
