yeah to rename the cookie you need to drag it over to "cookies to keep", right click the cookie and select "edit". it then asks you to enter the cookie's domain name. I just entered something like aergtwrt.com and then i moved it back over to cookies to delete. after running the cleaner it never showed up again.
Yeah i could never find the physical cookie. It didn't show up when i ran the cleaner on analyze (with both regular and admin mode), nor did it show up in the cookies folder for IE (and i had the show hidden files option selected). It only showed up in the cookies tab in options.
I ran the cleaner multiple times, rebooting after several times. I uninstalled AIM and that didn't fix the problem (and i am sure there was an "olivegarden" add on aim a few months back). I changed ccleaner to an earlier version and the cookie didn't show up, i then upgraded back again to the new version and the cookie popped up again under options/cookies. I then switched it to cookies to keep, changed the name of it, ran the cleaner and it vanished. weird huh?
