I really like CCleaner but when I just now updated to the newest version it added Yahoo Toolbar!!!! I do not want Yahoo Toolbar!!!! I don't know if I missed some small check mark low on the page, but as far as I'm concerned it was a sneaky thing for CCleaner to do. Hey, there are other cleaners out there. CCleaner: buh bye!
If you had watched when CCleaner was installing you would have seen the yahoo toolbar option. (You should watch when installing any software)
It is not sneaky to ask a user if they want to install something.
If you really like CC then you must have noticed that the Yahoo toolbar has been there as an option for yonks. Download the slim version and you don't even have to say no to the toolbar.
