I posted this awhile ago, but it hasn't appeared. This is a repost.
After multiple times running Ccleaner after exiting Firefox I still get the following results (please see the attached). 5 MB or more never get removed. Is there an option I have neglected activating, or is the current version I just installed not fully removing what it should? This never was the case in the past. I’ve been using the free version. Is this an indication that there is a back door left open by Microsoft to monitor my system?
