I had the same problem. I didn't have cleanup installed.

"Smart Scan has been scanning for performance issues on my win 7 computer for over 2 hours and has this little circle going around and it shows loading. When I click on skip it shows "your PC still has performance issues." I have no idea of what that means.
Could someone please explain?"

Ok then, so this is some UI Smart Scan issue - trying to include performance issues step when this component is not installed at all. We will try find out why it happens. In this case it might be helpful to have your avast5.ini, if you can submit it on support page. And thanks for you time.
