Hi, I am using Ccleaner (which I have successfully used on many computers that do not have Comodo installed) but am unable to really clean this PC. I run it and am told that x amount of files have been deleted but they haven't!! The Registry cleaner part works fine (Have 'searched' Ccleaner & know a few people had problems with that aspect). I 'inherited' this PC with Comodo already installed and feel sure that something is preventing Ccleaner (& 'Disk Cleanup') deleting these. Have tried changing settings within Comodo but without success!
