From what I've read, it's due to their including a line of adware script in one of the config or ini files. You can fix it by deleting the game.ini, render.cfg, and settings.cfg files found at Documents, WB Games, Shadow of Mordor, then launch the game and let it recreate new files, or recreate those files yourself using the script in the link I posted.
