Went through various uninstallation options to get rid of CCleaner, including: dragging to trash, using the 'Uninstall CCleaner' option from the App menu, right-clicking and choosing uninstall in the App folder, and drilling into the folders and using the CC cleaner uninstallation app. Nothing works. I keep getting: 'Sorry, something went wrong. Please try again. In addition, I can't even kill the processes using process monitor, as they keep restarting. Very frustrating.
