However hard I try to have CCleaner to delete all the cookies listed in the "Cookies to Delete" column of the Options | Cookies page, CCleaner (v. 2.35.1223) refuses to delete a cookie for "google.it". When I go to Cleaner | Applications, I can confirm that cookies are checked for all applications listed (Firefox/Mozilla, Opera, Safari, Google Chrome), and my cookies for IE8 are also deleted as reported under "CLEANING COMPLETE". Some time ago, I had a similar problem, and finally noticed that one of the applications did not have its cookies option checked, but this is not the case this time. Is there a problem with the latest version of CCleaner?
CCleaner can't delete files that are in use, have you tried manually deleting the file?
Curiously, there is no such cookie in the Cookies directory, so I cannot delete it. And as far as I can tell, I had closed open instances of IE before running CCleaner.
