You may want to try turning off "system restore" in
"system properties". Then reboot. You may also want to make
"system volume information" accessible to your malware scanner.
Then do a scan of that folder. The default setting is "read
only" and "hidden" so if it can be scanned the malware won't be
removed. The malware can reboot that last restore point over and
over and reinfecting your system over and over. A Linux based
scanner can be a way around the permissions but it's probably
better to do the scans within Windows.
