Preventing that attack is the job of the operating system. If the O/S is compromised there can be no security.

Eventually no program will run unless signed by an approved party. In the enterprise the approved party will be the enterprise, in the home the machine owner. 

Even signed code will not normally run with privilleges that allow modification of the O/S or installation of drivers.

That is a different problem that the O/S providers will have to figure out. That's not our job.
