Just in case you've not come across this one yet, its being reported on various sites in the last month.

It's another fake BSOD - call Tech Support scam, the icon it installs doesn't even look anything like the CCleaner icon.
I guess nobody here is going to fall for obvious junk like this, but it's as well to be aware that it's out there.
(Somebody is sure to fall for it then come here complaining).
