i had the exact same problem - after running a registry clean with CCleaner, iOlo Antivirus won't run. Restoring the registry fixes the problem, but then I'm left with an uncleaned registry.
Can someone please let me know which registry keys to exclude?
Better yet, please update CCleaner to correct this issue.
I just recommended CCleaner to a friend, but he uses iOlo System Mechanic with the antivirus program and now I have to warn him that CCleaner may mess it up
