hahaha im working on a project like this now...only its going to be wayyy better than just say you have a virus

it actually does something.....hehe
so far ive got it to change the desktop wallpaper
put itself in startup every time the pc starts up
annoying pop-ups
open mpgh.net at startup lol.
only way to close it is through taskmanager
shutdown the pc after "virus scan"

EDIT now it disables DESKTOP tab so that you cannot change your background form what i set it to!!! haha!
- now it sends me an email when the user is online :P
and yeah...i stole you idea of a fake virus scanner...it looks like yours only..more options and it scan the whole pc, and show the directory's its scanning. ;p
