All I'm saying is a reformat is the only way to be sure your system is clean. If you don't have any backups of your important files, you might as well cross your fingers and run a virus scan and hope it flushes out the spyware/virus.

Try AVG http://www.grisoft.com/
or Avast http://www.avast.com/eng/avast_4_home.html

You could also try Microsoft Anti Spyware though I'm not sure it would work on NT/2000 systems.

Good luck and holla if you get stuck.
