SystemWarrior is a rogue security application from the Wini family. It was the last in a long line of Wini rogues to use the older user interface before the release of AntiAid (you never know – they may reuse this interface, but there are a lot of rogues in this family using the old look.) Anyway these are pushed through codec updates. Usually you visit a web page that claims you need to download a new flash codec in order to see a certain video clip. When you agree to download you are actually downloading the installer for their rogue security software. Once on your system it will scan and find lots of files that it claims are viral infected and then pop up endless warnings about the security of your system. None of them are true, but they further claim that in order to clean up your system you must purchase their software. Please don’t purchase their software, but DO read on for how to remove SystemWarrior.
