So, the girlfriend's got a virus, and it's pretty nasty. I don't have the time to mess around with it, and she's not so bad with computers, but this is out of her league. (considering her idea of fixing the problem was to download a virus scan that was malware itself)

I think I remember hearing that it's possible to put in some restore/recovery disk that comes with the computer to bring Windows back to the way it was originally right from the factory. The problem is, I bought that computer off the shelf - literally - and I don't think I received a disk, or if I had, it's probably gone now.

Do you guys have any idea what I could do? I'm all for reformatting, it's just a toy PC for her. I just don't have a disk to re-install windows 7 with.
