How come in Options>Cookies> it still shows lots of cookies under "Cookies to Delete" even after I have run CCleaner?
Are some cookies impossible to delete?

Are you using a browser other than IE?
Do you have Cookies checked under Internet Explorer and Firefox?
Was your browser still running when you ran CCleaner?
Did you click on "Run Cleaner" button?
Sometimes there are problems with a few peoples files.
