Editors' Review


Junk food threatens your health, doctors say. Junk files threaten your computer's health in much the same way, by clogging up its data arteries with useless deposits that slowly strangle its performance. In both cases, exercise is crucial to maintaining the health of the overall system. Luckily, keeping your system fit and trim is easy, thanks to system cleaners like The Web Atom's System Ninja Portable. This portable freeware scans your computer for the digital equivalent of fatty deposits, such as temporary files and browser histories, and cleans them out, helping your system to run more like it did when it was brand new. System Ninja Portable also includes useful extras, such as Startup and Process Managers, a Checksum tool, and a system information display.

The portable version of System Ninja can run from any directory, including USB drives, but otherwise it's basically the same tool as the installed version. The user interface is simple and clean, with highlighted buttons accessing the Junk Scanner, System Tools, and PC Analysis features as well as the program's Options, which includes basic settings and an Ignore Files list. Like the installed version, System Ninja Portable found more junk than CCleaner, our daily driver. The results were similar, though, with both tools' options set to scan the same spots. Right clicking any entry in System Ninja's scan results let us delete or ignore the file or open its containing folder. To remove whole categories of files, we simply unchecked the appropriate entry and rescanned our system. Clicking Delete Everything took out the trash.

One advantage System Ninja has over CCleaner is the ability to choose which drive to scan. The program found 45 MB of junk on our D drive, more than we expected. The Process Manager and Startup Manager tools can help your system start up and shut down more quickly and run faster, too -- when used with care. The idea is to keep programs you don't need or use from running automatically, which hogs system resources and can even cause conflicts. We liked the installed version of System Ninja, and we like the portable version, too.

"HP printer users BEWARE"

Does as it says but... (see cons)


Deleted much-needed HP printer file(s). Why HP printer software installs crucial files as "temp" I have no idea. But they will be removed, and you will need to go through the process of uninstalling and re-installing even the basic printer drivers.


Would be great if it knew not to remove printer-related files. Use with caution!

"Good Program"

I use CCleaner as my basic cleanup program, decided to give this one a try. I was pleased with the results. I ran CCleaner first then System Ninja, System Ninja cleared out 80 megabytes of junk that CCleaned had left behind. The one thing that System Ninja does that CCleaned does not do, it scans all of your files, CCleaner does not. System Ninja installed without any problems and ran fine. Did not notice any undesirable effects with my PC after running the program. I will still keep CCleaner, as it is a good program, System Ninja is a nice compliment to CCleaner.


I have none at this time.
