I dont have C Cleaner but Google Chrome shows 12 times in processes. if you click on the little arrow on the left hand side it should open all the parts of C Cleaner.
if they don't show any usage under CPU they are probably ok to leave.
I suppose you could use Revo Uninstaller on setting 4 to remove it completely then reinstall it. But I would wait and see what others think.
You have to watch when downloading C Cleaner as it usually comes bundled with some crapware.
