CCleaner takes away the wrong cookies

I run CCleaner 3.00.1310 on two notebooks (Win 7 & Win XP SP3). Last night I used the software to maintain the former one, and afterwards started AVG free in order to let that program do its magic. It was set to turn off the PC when finished. This morning I found that AVG had issued 33 warnings - altogether only tracking cookies; "tradedoubler" and the like. When I started Firefox (4.0.1) I recognised my log in status on several sites was reset. So:

CCleaner left over 33 ad-cookies.

CCleaner removed the six cookies I had told it to leave alone.

This process has never before gone wrong. I darkly remember an option saying "let CCleaner intelligently decide which cookies to remove", but I cannot find it again. It was not intelligent at all anyway. So where is this option and how do you fix this twisted set of priorities?

Perhaps AVG interfered with the operation of CCleaner.

After you logged into the sites with changed status,

did you Analyse and determine whether their cookies were detected for deletion,

and did you have to reselect them for keeping ?

Perhaps something bad happened to your registry, which is where CCleaner typically keeps your settings.

NB 3.00.130 is as close as you can get to pre-release, it came out October 2010.

If the was a bug back then it would have been fixed by now.

I darkly remember an option saying "let CCleaner intelligently decide which cookies to remove", but I cannot find it again. It was not intelligent at all anyway. So where is this option and how do you fix this twisted set of priorities?

There is a "hidden" right click option in the 'Cookies to Keep' area when right clicking will reveal: Intelligent Scan
