It's part from an anti cheat service from Even Balance used in some well known online games. In perfect case this file is not harmful and necessary to play some games online. But be cautioned, it has a wide array of possibilities to sneak into your system (to see if you are cheating). Therefore Punkbuster could also be a potential target of hackers, to misuse it's capabilities to sneak into your system.

A part of Punk buster services. Very annoying and hard to fix. Most users will experience at least one failure or bug. Most users will have to allow it through their router and internet security settings.
every time i play battlefield heroes it's a Punkbuster eror
  Radu , installs this file for hl2 deathmatch. it's anti cheat, but I don't know who it stops, because some still cheat. when you shoot someone in the face with a double barrel and they kill you, I assume thet are cheating, so is this file worth the bother, you decide. not malware

The file is used by Punkbuster by Even balance it is used to prevent and stop cheating/ hacking on online games. Mainly used by EA games like Battlefield. Blocking this file will result in a kick from any punkbuster secured server with an error similar to the one mentioned above. It is not a malware or hack it is required for online play.
