Okay, if the starter motor won't crank when you twist the key, and your SECURITY light comes on, then the VATS system is triggering, apparently because it can't detect your using the correct key at startup time. But if you _can_ crank the starter, it'* not a VATS problem.
Do you have a second ignition key you can try? If your current one is dirty or worn, you might be getting only intermittent contact between the resistor pellet (in the key) and the ignition switch, and if the connection breaks while you're driving, the car won't shut down but the warning light will come on and (I think) the error code will set.
Your idle-speed/stalling problems might have something to do with the IAC motor, but the VATS system is not involved in that.
