  Perhaps I could try: the AV folks are trying to prevent the
execution of either modified normal binaries/files or 
specifically exploit binaries/files, by machines for which the 
files are executable or interpretable.

  The experience of those communities is predominantly
with DOS/Windows executables and interpretable files, which
they have difficulty generalizing from.

  In principle, they could be targeted at any machine, so any
mechanisms should be applicable to native executables and
interpretables as well as foreign ones.
