Bob -

A search on www.google.com turned up a link to McAfee's virus dictionary:



"This threat can be detected with DATs prior to 4230 with engine 4.1.60 as
"New Backdoor1" if the option to scan with "Program File Heuristics
Scanning" is enabled.

This worm may try to act as an IRC Bot, and to spread through KaZaA and
network shares. When run, the worm tries to contact a site which now
appears to be down, and to grab CD keys for games including Half-Life and
Warcraft III.

The worm then copies itself to the WINDOWS SYSTEM directory and references
itself in the registry so that it will be loaded again at startup:

"Config Loader" = sysldr32.exe

"Config Loader" = sysldr32.exe "

I'll leave it to you to go through the details of whether this is what you
have or not.

If you already ran the
web based scanner, you could try
  Symantec's security1.norton.com
web based scanner, since some malware interfers with virus scanners.
