That's good to know. I mainly run in a non-admin account most of the time and no one has physical access to the computer unless I allow it. Kerio is a good rules-based firewall, but IMO needs help from other security software. I have used HIPS before, but it requires the time , effort & knowledge to setup properly to benefit from using it. Of course with any good security/ privacy program that may indeed be what is required to achieve that goal.
