start with something like this to check your amavis virus settings:

There are other possible explanations too e.g. is amavis calling
clamav for incoming mails or is clamav being called directly by the
MTA? have you got clamav and amavis user permissions sorted (ensured
that clamav and amavis users are both members of each other's group)?
Hi Dominic,
Here is the info you requested (there is no amavis conf.d directory in
this amavis package):
# grep -r virus_ /etc/amavisd.conf | sed 's/\s*#.*//;/^$/d;/.*:$/d'|sort
@addr_extension_virus_maps = ('virus');
bypass_virus_checks_maps => [1],
$final_virus_destiny = D_DISCARD;
@virus_name_to_spam_score_maps =
$virus_quarantine_method = "local:virus/%n-%m" ;
(I am attaching the whole amavisd.conf for your reference.)
Postfix is calling amavis which in turn scans (clamav / SA) mail:
=============================== from postfix main.cf
================================
content_filter = smtp-amavis:[127.0.0.1]:10024
======================================================================================
Permissions are OK, because the setup works and *some* viruses are
identified and quarantined.
However, the thing here is that the main definition database seems to
not being used. What should we check to make sure that all definition
databases are being used for filtering?
Can we make sure that the main database is updated correctly and used
successfully?
By the way, freshclam.log shows successful database updates; for
example, today:
