|If you eliminate a nasty and your scanning software is not capable of scanning your restore folder, or the feature is not turned on, you may still have a copy of it lurking. Turn off system restore and then back on again to clean out the old restore points and reset a new one if you are comfortable it is clean and then rescan again. |
Back when I had a system with limited resources on the OS drive of an older XP machine, I would occasionally turn off system restore, do a disk clean up, then a defrag, and then reactivate system restore and PRESTO I had more room. Since most programs and files were already moved to another larger drive, and those remaining could not be moved, this helped a lot at the time.
