Put it into a script and call that :

set acl_m0      = cmdline:/..path../avirascanner.sh %s


+++++++++++ NOT WORKING EXAMPLE +++++++++++++++++++++++++++
#!/bin/bash

RC=`/usr/lib/AntiVir/guard/avscan -s --batch --scan-mode=all $1`
/bin/echo -e \N"\navira_retval $RC"\N:\N^avira_retval $RC\N:\N.*ALERT:
([^;]*) ;.*\N

Resolvs all problems you get with bashlike variablehandling. This
example has to be adjusted to your need of course.

I think, that whatever you tried to do with that echo does not work the
way you wanted it to.
