Did this ever get fixed? My Dad's computer has exactly the same issue. ANYTHING to do with CCleaner causes the application to crash. If I so much as hover over the CCleaner icon on the desktop or in the start menu the system crashes out (all icons and start bar disappear). Also, in IE AND Mozilla, if I type CCleaner into a search engine the window just closes and I lose all icons on the desktop for a few seconds. If I even search for it in windows that crashes too. Otherwise all these programs work normally.
