Whatever you do, do not trust Trust Ninja. It is a rogue security application that is very harmful to your computer. Though it is promoted through many ways, the most popular means of promotion are through Trojan horse applications and browser hijackers.

If your computer has been infected by Trust Ninja, then it will begin to slow down, as will your Internet connection. You will also be subjected to a barrage of fake security warnings and alerts from your taskbar. False system scans will also ensue in an attempt to get you to buy the full version of the program. While all of this is going on, your computer will be flooded by malware downloaded by this rogue.
Trust Ninja should be removed from your computer as soon as possible. In order to manually remove it you should stop the following processes:

TrustNinja.exe
TrustNinjaSvc.exe
uninstall.exe
