In CCleaner 5.63 There are 3 boxes ticked under Enable Automatic Browser Cleaning click on each browser and you get a drop down page click on disabled do this to all of them. Now click off Enable Automatic Browser Cleaning and click off Enable Smart Cleaning you do get a Warning Message click YES.
You now turned off Enable Smart Cleaning this is working for Me. if it does not work Reinstall CCleaner.
Good Luck Kas.
