System Ninja is a program for cleaning your computer of unwanted junk that constantly slows your entire system down. Apart from the useful file cleaner, the program also has a Startup Manager, Process Manager and P3P Registry History cleaning tool. Give System Ninja a try to see what it?s really capable of!

In this update the program has gone from something barely functional to a truly awesome program. The most important changes are the new UI and multithreading, meaning that the program no longer goes non responsive while scanning for files.

System Ninja Features
Powerful Junk Cleaner
System Ninja contains a unique dual cleaning engine. It scans your entire hard drive performing a thorough initial scan, identifying junk based on heuristics. System Ninja then continues to check locations that are known to contain junk based on a number of routines.
Useful Startup Management
The integrated startup manager allows you to dictate what can and canТt run when you turn on your computer. It supports Run, RunOnce and Sheduled Tasks files and registry keys. System Ninja contains a database of several hundred common startup items, used to provide information and advice so you know what to remove.
Powerful Process Manager
The process manager can forcibly terminate any process running on your computer. It can even remove multiple processes simultaneously.
Turbocharged With CleanSync
CleanSync is a new system added in version 2.1 that silently downloads new cleaning routines while System Ninja is running.
Supports Ninjascript
Ninjascript is a scripting language developed to rapidly add new cleaning routines to System Ninja. It can remove registry keys, files, directories and processes, plus identify files by name, extension or MD5 checksum.
Available in multiple languages
System Ninja is currently available in English, Dutch, Spanish, French and Brazilian. WeТre always looking for new translators!
