that is not a virus you numbskull, it is the world's best unzipping tool. Webroot catches a lot of stuff and it never said a thing.
Anyways...
Once my mom's PC got infected by a virus from Rio Antivirus software or something, the screen darkened, and it completely barred her from using the PC. A black and yellow shield appeared beforehand. She got customer support on the line, and she had to wipe the drive to get it working again. That computer has 512 MB of RAM and Windows XP 32 bit, so I am not surprised.
