Recently I noticed my computer was slowing up . in the past I have used a progrqam called “System Mechanic” which worked well. Now they have added a helpdesk subscription which has to be deleted within a month of use. I didn’t want to muck about with that so now trying out CC Cleaner with the trail pro version which seems to work well and no subscription. looks s if for £24 it is worth a punt , sogiving it a bit more time on the trial first
Also have a read up on PrivaZer. There’s a free and paid version. I’ve been using it a few years without issue. Might have to set a few login and preference cookies when it has finished cleaning.
