STRs 801 and 700 are good examples of strands of hay mistaken for needles. Returning to Gatekeeper, the symptoms are not quite "hard-wired". Gatekeeper's philosophy is, basically, that if a virus can't move, add, modify or delete executable resources (there are about 24 types), then it can't spread. And a virus that can't spread isn't really a virus anymore. Of course, you'll still want something like Disinfectant to remove the effectively sterilized virus. The list of executable resources is certainly not hard-wired - it's easily edited by following the instructions in the on-line help. The type of monitoring that Gatekeeper does *is* hard-wired, but in order to establish that this is a problem, a way must first be found to spread a virus without moving, adding, modifying or deleting executable resources. In short, the hard-wired aspects of Gatekeeper are not a problem - they are *fundamental* protections. This is why Gatekeeper has been able to stop every Mac virus discovered to date, including totally new viruses like ANTI and INIT 29 which were developed *after* Gatekeeper was written. I should add that Gatekeeper's security system has not had to change since it was first released on 2-Jan-89, precisely because it is such a fundamental approach to stopping viruses.
