Your beliefs - when they are contrary to reality - don’t matter. I have ran multiple tests with multiple monitoring applications and the only time the DRM code is executed is when protected content is playing. The code isn’t even loaded into memory unless such content is playing.
In short - you are wrong.
I don’t see how. How would the DRM code know to execute unless there is some process sitting there waiting for you to start to play protected content? It may very well be a part of some otherwise innocent process that raises no suspicion, like explorer.exe or something.
