Something has been wrong with my finder and Mac. How to fix? Finder is often unresponsive.

Also in many software, like xcode or any project. I used to be able to right click and select open in Finder. Now if I do that nothing happen.

Zip utility is much slower. Takes minutes to solve.

I think this happen since I used ccleaner or something.

How to fix?

Finder seems to be the one affected. I wonder if there is other apps with option to "open in Finder" like xcode.
There is a bug in 10.8.2 where occasionally revealing files in Finder stops working and Archive Utilility stops responding whenever you try to extract an archive.

As a workaround, you can terminate appleeventsd from Activity Monitor or with sudo killall -kill appleeventsd. (Without -kill other processes stop responding.) The issue will probably return within a few days or hours though.
