So I installed Norton Utilities 15 on the Win 7 Pro (64bit) desktop within the administrator's account. So far, no issue.
However, while working within a user (regular-type, non-admin) account I run the disk cleanup option. Then in browsers tab, run that option. Message flash and things are getting scanned & cleaned, BUT, it is only cleaning App Data within the Admin's account and not the User account that I am logged into. So all the IE cookies in the user account do not get removed.
I have gone into administer/setting and set the C: drive in Scanning Paths. Even added folders pointing to each user's AppData folder. Didn't help.
I have confirmed this by running CCleaner before and after only to view the cookies, not remove them. CCleaner will of course remove cookies.
