I have a disk called Majik 12, a compilation of various utils that I find very handy. On it is a program called Master Virus Killer, which eliminated every virus I could throw at it. It could also detect (but not really fix) disk errors and place an actual protection on your disk (just in case you don't want it erased accidentally). It was also very easy and fun to use.
I say fun because, when a virus is detected, an alarm sounds. To kill the virus, you have to click an icon of a gun. Then you hear a gunshot, a scream, and a malicious laugh, and you have no more virus.
