CCleaner is more effective on your temporary files,with the participation of the most reliable web browser now which is no other than of course the one that i am using now the firefox 3.0,the browser that known as... bug free browser,so if you wanna like to have your computer scrub go with the CCleaner now!, but ah ah ah...CCleaner-users should pay attention to the program check boxes during installation. With two shortcuts, Recycle Bin buttons, and a browser toolbar, the application's default extras can get a bit much. For me, the application and Start menu shortcut are sufficient; though since I use Launchy to quickly open applications.
