I use ccleaner regularly. I have just downloaded ver. 3.10 from Piriform and installed it. There is a screen asking if you want to load Google Chrome with the checkboxes ticked by default.
CCleaner is one of the few FREE pieces of software which doesn't insist on either loading unwanted 'extras' nor altering any of your settings.
Not sure where you got your copy from Cornish Jack but if you didn't get the option NOT to install Chrome then it was a bastardised version of the real McCoy.
Chrome is, in my opinion, a damn good browser anyway!
