AtomicCleaner is one of the software tools designed to boost computer speed by removing unnecessary files, providing a very pleasant interface to help it in this regard.

There are four different pre-defined cleaning modes, plus an advanced system for more experienced users who wish to select manually the things to be cleaned.

Relying on a user-friendly and intuitive interface, AtomicCleaner lets you perform a full clean, which removes all unnecessary files, as well as a so-called “Gamer Cleanup” to remove unnecessary files left by games, both online and installed.

If you're one of the users who spend a lot of time on the Internet, you may want to have a look at the dedicated “Internet Clean” which speeds up browsing and removes browsing history and traces. Last but not least, “Temp Files” does exactly what its name suggests and deletes browser and system temp files for a faster machine.

The advanced mode lets you pick anything from gaming files and cookies to browser passwords and log files, giving you the option to force removal of read only files, hidden files or empty folders. Additionally, you can clean up the Recycle Bin to make sure no unnecessary file remains on the hard disk.

AtomicCleaner does indeed a great job when it comes to deleting all leftovers, but Windows 7 users need administrator privileges to be able to run the application.

The “Settings” menu gives you the option to schedule a clean at any user-defined interval, enable transparency and even protect the system with a password.

All in all, AtomicCleaner is undoubtedly a handy software solution, not only because it's free, but also thanks to the fact that it provides so many customized cleaning modes for many types of users.
