I haven't downloaded any such files/folders, but I have a few of them anyway. One such folder is listed as "xerox" in my Program Files. It contains nothing but a directory called nvwia which is empty. When trying to delete it, it says the file nvwia is in use by another user or program and to delete it, close that program/log off that user. This is a standing problem that has been with this computer since I got it second-hand from my mom's boyfriend. It was his company's server.

Sorry for posting it with this forum, but this is the first ever I have seen on the problem.

The machine is a Compaq (I know, HP, now) Proliant ML370 G2
WinXP Pro SP2
P3 1.266 GHz
1536 MB RAM
4 RAID-discs (total 200+ GB)
HP NC3163 Fast Ethernet NIC 10/100 Mb
