Comodo System Cleaner collects three free and useful cleaning utilities: Registry Cleaner, Disk Cleaner, and Privacy Cleaner. Running these utilities will rid your computer of duplicate, harmful, or otherwise unnecessary files.

The interface of this program is colorful and easy to navigate and use. Before it runs a cleaning task, it creates a backup of your system to prevent any accidental loss of data, which is a great benefit. Day-to-day computing inevitably causes stray files and other debris to build up in your system, and it's often difficult to find and delete it all. We ran each of Comodo System Cleaner's utilities on our laptop PC, and it cleaned out a whole bunch of unneeded junk on our system without deleting anything we didn't want it to delete or otherwise damaging our computer's functionality. The process was swift and efficient. We already had a couple of different types of virus and spyware protection software installed on our computer, yet Comodo System Cleaner was able to find junk that the other programs had missed. We don't suggest running this program in lieu of your standard antivirus and spyware program, but it's a nice complement, and we plan on keeping it installed on our system. We found this program to be very easy to use; however, there's a Help file available as well as support from the manufacturer.

Comodo System Cleaner is as well-designed and functional a program as its competitors, yet it's free, which makes it the best bargain there is.
