CCleaner gets stuck and will not finish

When I try to clean my registry CCleaner free version gets stuck at 60% and will not advance to finish cleaning no matter how long I wait. I have attached a screenshot. Please help me sort this out thanks. :)

sounds like it's trying to remove something that shouldn't be removed (prime suspect is a entry protected by your antivirus).

Are you blindly cleaning the registry (clicking fix all as opposed to one by one evaluating whether or not to remove each entry)? Best practice is in my signature below this post.

If you are being discerning then please attach a debug report showing the freeze happening. Instructions for that are here

Nergal, Thanks for your response and detailed information. :)
