thanks for responding, nukead!
I have been updating ccleaner regularly and never had a warning about closing explorer, which wreaks all kinds of havoc for me if I let a program close it or need to close it myself, just had the same issue with alldup wanting to close it when updating and I let it against my better judgment and then had to reboot just to restore explorer properly.
I have always had other mrus checked and just never saw that before and can't imagine why any program would ask to close explorer knowing the mess it would make; I assume it was being skipped as you said. Anyway I have unticked it now, and nothing in the program is ticked for smart cleaning, so I had to find a new entry in startup programs enabled in registry so I deleted that. That is a new and unwanted intrusion, because there is no way in options to disable it, and I have always had ccleaner set to check for updates, which it only ever did when I ran the program. Disabling the registry entry for smart cleaning got rid of the icon, but that's very sneaky and verging on what avira is doing now. AIO programs don't work, nobody needs them, ccleaner was fine the way it was and the more it tries to do the worse things can get.
