Windows ME/XP Users: Turn off your "System Restore" BEFORE running a complete virus scan, SpyBOT Search & Destroy scan and fix and Trojan Hunter scan and fix!
If you don't, any problems that were found and repaired (fixed) may still return again to cause you grief after you reboot your system. This is due to the "System Restore" feature setting your system back to the previous time when your problems were still in there.
After you have completed all scans and fixed any problems found, reboot your machine, then turn "System Restore" back on.
Hope this helps...
