PunkBuster

PunkBuster is an anti-cheat system made by Even Balance, Inc., which has been fighting cheaters in online games since September 2000. It helps players and administrators of game servers deal with cheaters: PunkBuster runs on both the game client and the server, and it continuously scans computer memory during gameplay for signs of known cheat programs, much like an anti-virus scanner. It also detects modifications of the game environment and verifies game integrity. The software updates itself in the background, so new detections reach players while they play, and Even Balance researches game-specific countermeasures for every supported title. For cases where the automatic update fails, Even Balance offers PBSetup, a small utility that manually updates PunkBuster for one or more installed games. In PBSetup you click "Add a Game", choose the game from the list, confirm its installation path, and then click "Update PunkBuster". PBSetup keeps the list of added games with their installation paths, so the update can be repeated later. Games currently listed by Even Balance include America's Army: Proving Grounds, Battlefield 3, Battlefield 4, Battlefield Hardline, Far Cry 3, Ghost Recon Future Soldier and Red Orchestra 2: Heroes of Stalingrad. The PunkBuster client is free for players, and PBSetup is available for Windows, with separate versions for Linux and Intel Mac OS X games. 

Features:

• Anti-cheat experience since 2000.
• Free for players.
• Continuous memory scanning
• Windows, Linux and Mac versions

Keeps PunkBuster up to date, so you can join protected servers of supported online games without update errors.

Server administrators also get tools such as screenshots of players' screens, ban lists, logging, streaming and remote access. Many newer games use other anti-cheat systems, but PunkBuster is still required to play the supported titles on protected servers.
