No if u do that you might as well REFORMAT the whole pc and get it back to FACTORY reset (but note that you will need to reinstall XP) unless u have REFORMAT discs that will save you from having to wipe the HDD clean (but i doubt you got restore discs as u got a copied XP) btw most dodgy shit comes from a downloaded version of software i.e. XP if u got it via P2P that is
