Conspiracy theory time!
My theory is that the anti virus companies are the very people who create the viruses to create more demand for their products. AVG, McAfee, Norton, etc are the ones who are making the flippin' things!
That wouldn't be the first time I have heard that theory. it's best when you get some malware that pretends to be a bit of antivirus and tries to scare you into buying it to get rid of nonexistant viruses.
Hmm, funny. I use Windows XP Pro without any anti-malware protection at all and I never have any problems at all. It's an old habit from when I still only had A Pentium 3, but I've found that I have no use for said software at all.
What the hell do people do with their machines :p
I don't do anything dodgy in windows these days. i tend to do everything through linux lol. But my wife has a nasty habit of downloading these stupid smily packs for stuff like yahoo, and every virus riddled, data mining, facebook game. I would say that once I week i have to recover the PC to some sort of normality due to the crap she installs. And I have no idea how the hell stuff is getting on considering I installed kaspersky.....
OMG KESA YOUR FLAMING RIGHT!!!!
