I had the same problem. Never could find a virus, but discovered the
Trojan: BackdoorHackarmy.BN. My virus scanning software kept giving
me positives in a directory that wasn't showing: c:\Documents and
Settings\******\Local Settings\Temporary Internet\IE Explorer.
Somehow the directory was being masked. After letting the virus
scanner do it's work. I used Eraser to erase the "Temporary Internet"
directory. When I used Eraser, it prompted me to erase 5 directories
and 907 files that weren't showing up! I'm still not sure what was
masking the directories. Please post any information you might find
back to this group (the email address is phony). This was a really
nasty SOB.
You might want to download TDS-3 to check for Trojans. TDS-3 is the
most comprehensive trojan detector out there. You can download the
program here:

PortExplorer, from the same website, to see if you have any
compromised ports. If you are being hacked, PortExplorer lets you spy
on the information the hacker is obtaining. You can get PortExplore
