Still trying to figure this one out. We run Windows XP SP3 with 5 user profiles. For some reason the 1st personal profile setting was wiped clean except for the start up programs. All documents,files,wallpaper,screen saver ,iTunes,they all disappeared. All the Virus/Malware scans come up with nothing. Of course this user didn't back any of this up so his stuff is gone as far as we know so far. Thanks for any input.
