If I run CCleaner followed right away by Spybot and Lavasoft Adaware, without any other applications running, or browser sessions, etc. Spybot & Adaware still find cookies. For example I just did it and Spybot still found 25 cookies.

Is CCleaner not removing all cookies by default? The list under "Cookies to Keep" is empty.

This has been going on forever, it's not something new in the recent versions.

thank you

welcome to the forums
make sure you have that option checked to delete cookies.
then go to ccleaners settings and theres something that says only delete cookies older than 48 hrs.
uncheck that and it should start working fine

Of course I have the cookie cleanup option checked.

The 48 hrs. option applies to the Windows Temp folders and it's unchecked.

As I said, it doesn't delete *all* cookies, some are still left behind.

Do those ccokies show up in the Cookies to Delete list? CCleaner sometimes seems to not "see" cookies that existed before CCleaner was installed or upversioned.

Try manually deleting the cookies once.

Well, I delete them with Spybot and Adaware and then a few days later, same thing happens: run CCleaner, deletes most of them, but then again Spybot and Adaware still find a couple more. Next time it happens I'll try and track it down, where these cookies are, etc.
