If you have purchased Battlefield 2142 from EA games, you are allowing EA to install spyware/adware on your pc to monitor how much your game client looks at a certain advertisment. This is included in the EULA you agree to when installing the game stating that the can collect \"anonymous data\" which means anything really ( ie pc specs, account info,bank detials )
