I have found a case where the CCleaner registry cleanup crashes the computer and I do not think it is CCleaner but I am looking for possible solutions - When you check of the INSTALLER option int he registry clean, the computer reboots, immediately. Now - If you open regedit and browse to the installer directory in HKLM you can open all subfolders EXCEPT the FOLDERS directory - As soon as you click on it, the system crashes. Run Ad-Aware or numerous other utilities - As soon as they access that particular registry folder - Boom crashes.
Load the Hive into another computer or using BartsPE - Crashes. Run a virus scan, crashes the moment that registry entry is accessed. Run dial-a-fix to reset all permissions, no effect.
Does anyone have any ideas on this besides reformatting?
