While BD provides scheduled events, it also required the computer to be awake and the user logged in. If not meeting those requirements the scheduled task will execute when you wake and log into your account. Very disruptive! (So much for scheduling events.)
System: Windows 7 Professional 64 bit with BD Total.
First: What don't I know that could make the system wake on schedule and scan?
Second, if no direct solution is available: I am happy writing my own scheduled task. Does anyone know the command line prompts for the default deep, full, and quick scan?
