Now, if you are running something that changes the game play so that you have an advantage over everyone else, aimbot, no reoil, wallhack etc etc, then that is a whole different story. If I wish to kill the Steam task, I can do so. Steam has not control over my personal PC in regards to what I run or when. I can terminate any process on my personal PC that I wish to as I wish to. Not really sure how steam is able to record how it was terminated, but in reality it should not really matter.
