The program has three main modules: a Registry cleaner, a privacy cleaner, and a disk cleaner. The Registry cleaner finds problems and errors in your Registry and gets rid of them, while the privacy cleaner rids your system of traces left behind by Internet browsing and by applications. The disk cleaner kills various caches, log files, unused icons, and more. Also included are other useful utilities, such as a duplicate file finder and a small application for showing you system information.

What distinguishes Comodo System Cleaner from similar programs is its extreme simplicity. It's as straightforward a program as you'll find. Click a few buttons, and you're done. You won't have to fiddle around with options or confusing menu choices.

If you're looking for a simple way to clean your system, with as little muss and fuss involved, it's a great bet.
