I feel for you, but your expectations are out of whack with reality. Any Windows laptop, properly maintained, is a reasonably secure device.
You can "restore" "reasonable" security to your Mac even in the almost unthinkable light of a possible actually available exploit, that can be reasonably be expected to affect you personally, by using a strong filevault password. Maybe you want to add a tripwire (file integrity) check at boot time, or a manual check when you mount any drive.
No, the precedent you ask for does not exist. In fact, the opposite is true.
