assuming your using Windows ME and not XP or another OS that supports system restore try this. start up the defrag program then pause it (dont stop it, just pause) then go into the 'c:\ _restore\temp\' folder, delete the virii (better to hold the shift key while deleting so they do not become locked again while in the recycling bin, if that is possible). defrag.exe unlocks some of the system files while it runs, like the restore folder so it will not stay fragmented.
