I know that MIMEDefang supports multiple virusscanner and one can use several

e.g.
if clamd dies, do not TMPFAIL immediately but try first to run calmscan or 
uvscan or
others....
Code your own message/entity_contains_virus function by to call the 
appropriate entity_contains_virus_clamd (a.s.o.) function directly.

E.g.: This was the function before it gone into mimedefang.pl:
sub message_contains_virus () {
    return message_contains_virus_avp()      if ($Features{'Virus:AVP'});
    return message_contains_virus_fprot()    if 
($Features{'Virus:FPROT'});
    return message_contains_virus_fsav()     if ($Features{'Virus:FSAV'});
    return message_contains_virus_hbedv()    if 
($Features{'Virus:HBEDV'});
    return message_contains_virus_nai()      if ($Features{'Virus:NAI'});
    return message_contains_virus_nvcc()     if ($Features{'Virus:NVCC'});
    return message_contains_virus_rav()      if ($Features{'Virus:RAV'});
    return message_contains_virus_sophie()   if 
($Features{'Virus:SOPHIE'});
    return message_contains_virus_trophie()  if 
($Features{'Virus:TROPHIE'});
    return message_contains_virus_sophos()   if 
($Features{'Virus:SOPHOS'});
    return message_contains_virus_trend()    if 
($Features{'Virus:TREND'});
    return message_contains_virus_filescan() if 
($Features{'Virus:FileScan'});
    return message_contains_virus_clamd()    if 
($Features{'Virus:CLAMD'});
    return message_contains_virus_clamav()   if 
($Features{'Virus:CLAMAV'});
    return message_contains_virus_carrier_scan() if 
($Features{'Virus:SymantecCSS'});
    return (wantarray ? (0, 'ok', 'ok') : 0);
}

So you could move to _clamd() check first, but instead to return 
immediately check its return value and proceed with the next scanner, if 
it returns with TEMPFAIL.
