Antivirus XP 2008 - Who of you fuckers invented this. I know it's one of you

Fucks up your computer, demands you to purchase the anti-installer else they keep fucking up your computer. They'll change your properties, randomly shut down your computer, randomly remove internet settings/passwords, change your desktop. I never download any plugins/shady stuff. But i did surf some adult sites without popup blockers but I'm guessing it was a auto-installation without request.

These arent small cats & dogs doing this. This is the most nasty thing installed on my computer EVER. They are wanting ?40.00 (some heavy cross-saling on their join forms too), but they aint getting mines surely. Anyone has experiences with this already, how to de-install it?
