Alas, we've been here before.

  Exactly.

  Please come up with a set of requirements that can be reviewed by the 
  core kernel folk, and perhaps then focus on how to meet those requirements
  once they have been accepted.

To be very clear, so we don't waste any _more_ time and effort on this: 

The anti-malware folk need to first provide a clearly understandable and 
complete description of the problem including a characterization of the 
threat.

The next step is to propose a design which addresses the problem, and to 
clearly and completely demonstrate how it does so.

Only then will it be possible to conduct an informed discussion on the 
underlying case for malware scanning and its possible implementation.
