Two primary internal av scanner - get stats

Hi all,
I use Two primary internal av scanner:

Using primary internal av scanner code for ClamAV-clamd
Using primary internal av scanner code for IKARUS scan.server

now I wish to know how many virus clamd are blocking
and how many IKARUS.

When a virus found, I get in log "Blocked INFECTED" without any
information about which av scanner detect virus.

I really do not understand if amavis use av scanner in sequence or in
parallel.


TIA
Alessandro
