My entire network is infected with the marioforever.exe rootkit. And when I mean my entire network, I mean it goes all the way from my servers to my user's computers and I think it recently killed my plotter printer (though the plotter is just speculation). Does anyone know an effective way to get rid of it from the servers? I'm going to purchase an enterprise class anti-viral software such as avast to get rid of it (prior it guy never installed any kind of virus protection). I found that when I scheduled a boot time scan on my PC (vista) that it was able to rid my system of it, though I'm nervous about letting a program such as avast quarantine and delete system critical files that aren't locked down...I just don't want to kill my servers over a virus and am fairly new to this game. My main DC is an SBS 2003 server R2, and all my other servers are win 2000.
