Using this strict settings above I have no problem also on very old 
servers .

Using above conf on an old pentium IV celeron I have this stat
44 virus detected with 7 days working and 57747 messages processed .

If I use a less strict configuration , I have serious problem too.
With current configuration , 0 problems.

Talking about cpu usage I have read good things about Mail::ClamAV  
http://search.cpan.org/~sabeck/Mail-ClamAV-0.17/ClamAV.pm
assp uses instead File::Scan::ClamAV , I don't know which is better .
