CleanMyMac is a maintenance tool that takes care of correcting and fixing all of the little problems that your computer has, keeping it in perfect shape.
The program will quickly scan your computer and identify all of the 'garbage' files on it. It will ask you if you want to delete them and allow you to free up a lot of space on your hard drive by doing so.

Very complete and works almost perfectly. The anti-malware feature should improve slightly, as it is a bit lacking.
