I would certainly agree Scot's criteria was... a bit funny.
But interesting nonetheless. I would dearly love to do my own "real" antivirus test! I'm amazed there is no real "open" antivirus test out there. I would imagine a good public collaborative effort could assemble hundreds, perhaps thousands of viruses, trojans, spyware, etc. to infect test systems with. That would really be the measure. It would even be good to get a few "white hat hackers" together to custom-code a new antivirus for heuristic testing.
Oh but I digress...
