ahw30045, To completely rid your computer of that trojan you must disable System Restore then restart your computer and run another virus scan which should come up clean. If it comes up clean then enable System Restore again. Disabling System Restore and restarting your computer purges all the System Restore files including any virus/trojan infected files. I'm assuming your using Windows ME or XP so I'll post links with instructions for both operating systems.
