It sounds like you're infected with a variant of the Spybot worm, that some
AV scanners are not catching.
See
www.dougknox.com, Win XP Utilities, Create Emergency Copies of Critical
XP System Utilities. This small VB Program will create backup, usable
copies of Task Manger, Regedit and MSConfig (named Taskmgr1.exe, Regedit.com
and MSConfig1.exe) in a new folder C:\EmergencyUtil. Many virus programs
will intercept these programs, based on their original file name. The
modified file names, allow them to be run. Open Windows Explorer to
C:\EmergencyUtil and double click the application you need. The next
revision will allow you to browse for the folder you want to place the
backups in.
Additionally, see the Win XP Utilities section for Startup Programs Tracker.
This small utility scans your system for startup programs and running
processes. It also allows you to create a log file that can be copied and
pasted into a newsgroup post. The contents of the program window are also
copied to the Windows Clipboard, automatically. For replies to newsgroup
posts, do NOT include the Running Services, unless its absolutely necessary.
Then update your AV software, and scan your system, preferably in Safe Mode.
You may also want to try different "online" virus scanner's from different
vendors.
