I would shut off system restore, turn it back on and then do the scan to make sure they are gone. Or you could do 2 scans, one with it turned off and one with it turned back on,. It's your choice but I would definately do one after you have purged the system and have system restore turned back on just to make sure everything is normal. Directions are here.
