System Ninja 2.4.5

System Ninja is a fast, powerful and effective system optimization solution for Windows XP, Windows Vista and Windows 7. It is designed to quickly remove unwanted files, increase system performance and help fix problems. System Ninja’s file scanning engine removes junk files from your computer. It performs a heuristic analysis of every file, identifying what doesn’t belong.

System Ninja is provided absolutely free of charge, with no strings attached. 100% free from viruses, malware, spyware and all that other unwanted junk.


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 can’t 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. We’re always looking for new translators!

I ran CCleaner then re-scanned using this straight after and found almost twice as much as I had using CCleaner. I'll probably continue to use CCleaner however as I've been using it for years and had no problems with it whatsoever, plus it usually takes more than one scan to get rid of all the junk and Ninja seemed to take slightly longer to scan.
