Thanks for the response and info. I'll check into it further, using your
suggestions. One thing bothers me however; Having formatted the hd, and
reinstalled xp, and nothing else, why then would there still be malware on
there, and why did it freeze the very first time I tried to use
networking?, (Not the Net but computer to computer) I had also run several
spy/add ware programs before I got radical and wiped 'er clean, as well as
scanned for viruses, with no problems reported. I have since run the
detectors yet again, with no reported problems. I ran Hijackthis before and
after as well, and had searched the web for every entry that even looked a
little suspicious, ("before") with good results for all. I am a VERY careful
NET user, and do regular maintenance to make sure I don't have problems. I
use a firewalled router, and keep resident programs running in the
background, just-in-case I do run into something adverse on the web. So I'm
a little perplexed here.

Cheers
Keith
