Description: Comodo System Cleaner continues to improve since the first time I saw it. It has three main cleaners (disk, privacy, registry) and a "clean my computer" one-click button to run them all. It uses a two step "safe delete or registry protection" procedure to prevent you from deleting essential files or registry entries, including a built-in backup and restore tab and a restart of the computer. The second step requires you to restart the computer before finalizing its actions. In addition, it allows you to set a new restore point before cleaning for a third safety precaution. Why all the fuss? Well, automated cleaning is risky business, so also be sure to have a good backup of your files and a drive image.
It also comes with many other cleaning and system utilities. You can manage autorun entries (startup-up programs, services, etc.), erase selected files/folders or the free space, view system information, uninstall software, and tweak system settings. It downloads a help file through an updater if you need it; otherwise, the internal updater is disabled in the portable version. Creates files and folders in your user folder ("ComodoGroup" in "roaming").
