Re: Reinstall XP and Keep Old Files?
I think the best way, as rok.my.sox said, would be to back up your files and format your hard disc, especially if you're trying to get rid of a virus.
Otherwise, if you have a HP (or a Compaq also, I think), there is a command to bring your PC back to square one (believe me, I have used it a lot). It is called "System Recovery" on HP, and on Compaq, during the boot-up, if you press F8 (i think) you get the same kind of thing.
That's all for now. Hope it helps.
