The following works fine for me (adapted from the generic script -- which
should work as well since it blocks all exe files by default)

if $message_body matches "(?:Content-(?:Type:(?>\\\\s*)[\\\\w-]+/[\\\\w-]+|Dispo
sition:(?>\\\\s*)attachment);(?>\\\\s*)(?:file)?name=|begin(?>\\\\s+)[0-7]{3,4}(
?>\\\\s+))(\"navidad.exe\"|navidad.exe)[\\\\s;]"
then
  fail text "\tThis message has been rejected because it appears to\n\
             \tcontain the W32.Navidad worm. See:\n\
             \thttp://www.sarc.com/avcenter/venc/data/w32.navidad.html\n\
             \tfor details. Please contact postmaster@??? with\n\

  seen finish
endif
