You have a great program, and thanks for making it.
I hope I can help you by reporting the following bug. This applies to v 1.36.430
In the scan registry portion of ccleaner the program finds the following keys to be deleted.
HKEY_CLASSES_ROOT\CLSID\{CA9231BB-C5D9-4B62-BD73-DBB66DDD2F7C}
HKEY_CLASSES_ROOT\CLSID\{64AA1D7A-2D19-48F5-B075-25F09F072758}
HKEY_CLASSES_ROOT\CLSID\{16A02704-8F8B-40DA-8458-7DEC285EA197}
These keys should not be deleted, as it will cause The Computer Associates CA Firewall to have a runtime error when Windows XP 32 bit starts up.
The firewall has to be un-installed and then reinstalled to fix the issue.
I hope this helps, and thanks again for ccleaner.
