ATF Cleaner question

I finally talked my husband into using SuperAntiSpyware and SpywareGuard. But he doesn't use ATF Cleaner as he is afraid it will wipe out all his passwords. Is there any way ATF Cleaner can be used and still keep passwords? He says he goes through AVG and deletes temp. files but whenever he scans with SuperAntiSpyware it always shows he has cookies.
Thank you.

 

I use ATF-Cleaner and CCleaner and haven't had any problems. If you use IE there is no option to remove passwords in ATF-Cleaner. If you use Firefox, then there is a box you can simply uncheck before running. Even if you do accidentally check this box, you will get a confirmation requesting permission before they are erased.
