Hullo. There's this malware that a couple of AV's (nod32, ess, kapersky, etc) can't detect (but avira can detect it). Avira says it's a backdoor trojan C:\Windows\pc-off.bat. Apparently, it is also associated with other malware like password_viewer.exe and bar311.exe. People describe it as shutting down their pc. Some say there is also a timer before the shutdown. I'll send you a .zip sample as soon as i can find one. email@example.com right?
