For those who download it and didn't run it, you're safe. Remember, the .dll need it to run. AKA: The injector, I can with Malewarebtyes and I just found simple fake ones. Like three, I removed them just in case.
However, users with Steam accounts, keep proof and data on a CD or nearby. Legify could tell your hack too.
As a precuation to the people, I will be shutting off the Xfire hack if it have not been removed because. I do not wants the risks of that other hack.
Please, understands this proble, and have fun!
For those who indeed ran it, please notes to make sure you scan and look carefully, sometimes what is there isn't what it seems.
