I have a similar problem. After running a privacy cleaner and restarting a computer, a dialog box with finalize button appeared and Spybot S&D told me that CSC tries to change something in a registry. But i was not able to allow this request , because my computer stoped responding. After rebooting second time, everything was fine, and i pressed a finalize button. Unfortunately, CSC deleted my firefox cashe, despite the "Mozilla Firefox" checkbox was unchecked. Then i ran CSC again, and when i pressed "Analyze My Privacy" button, my computer rebooted again.
System: Windows XP SP2
Security software: CIS 3.5.57173.439, Avira Antivir 18.104.22.1687, Spybot S&D 1.6.0
Sorry for my bad english.
