Yeah well the file name doesnt sound like a file in BFHeroes so I think your Anti-Virus THINKS it comes from that location. Or the virus gets executed by starting it as a camouflage. I dont know, but it isnt BFH that makes you get virusses
It would have been helpful if we were shown the full file path.
This isn't a standard thing that came packaged with BFH otherwise my comodo would have picked up on it. So you must have DL'd something dodgy at some point.
After a quick Google this trojan is designed to steal game account data so it is probably prudent to change the email address and password for the account you were logged in as.
