I've discovered a pretty severe w32.sality infection at one of the sites I work at. It's affecting several machines - my expectation is it's on them all (about 25 or so). Normally I'd just scan using a LiveCD and delete the infected files, and be done with it. But this particular virus infects so many executables, that if I delete them all I'm worried I'll end up with computers in a rather borked state. So might I be better off reinstalling?1 person needs an answerI do too

The likes C:/Windows/system32/rundll32.exe are I believe rather important for Windows to function properly. That file is turning up virus-infected - I expect having deleted it is going to at the very least send me running for my Windows CD to do a repair or something right?
