CCleaner

Hi,

I've been in the habit of using CCleaner to periodically delete cookies that are not useful. Now I see that Do Not Track Plus has added a bunch of "opt-out" cookies. How to I recognize them, so as to avoid deleting them. That is, I want to add them to the "Cookies to Keep" area in CCleaner. How do I tell which are the "opt-out" cookies?

Thanks!
