I'm reasonably sure that my personal machine is less compromised than the average, but I can't and will never be able to ensure that it is not compromised because I have no way to know everything the machine trying to do. This remains true even when you have an entirely free and directly inspectable hardware; you simply have no knowledge and time to verify everything. Just keep a reasonable amount of precaution and skepticism.
