Once installed, AntivirusXP 2008 will scan your computer and report a bunch of security risks found on your computer that can only be removed if you purchase the software. The risks are all fake and are being displayed to make you think your PC infected. The scumbags behind malware like this their money when you fall for the warning and buy their bogus software...which will most likely just install more Trojans, Worms, and Keyloggers so they can keep spreading the infection.As always, I highly recommed that you run a layered defense on your PC as I outline in my Security Toolbox to prevent attacks like this from occurring.
