ok, I checked the hard drive, no errors. I install an old version, the same problems. I think the problem here is: CCleaner scans for Windows.log. Windows.log = 0 KB. CCleaner can not delete 0 KB file. CCleaner can not skip windows.log search. CCleaner search for windows mediaplayer. Windows MediaPlayer has been deleted 14 days ago. CCleaner can not skip the windows media player search. he looks about 10 minutes the media player, only then can the search continued.
