amavis not calling my own antivirus

More likely reason is that Amavis maintains it own cache of mail scan
result to improve performance.
As per the changelog from  Amavis 2.7.0 this functionality has been
disabled. But the manual page still mention about the caching of result.
If you are using older versions add the following scalar in amavisd.conf
$enable_global_cache = 0;

There are also other parameters important regarding this.
$enable_db = 0;
comment the $db_home parameter, delete the db files $MYHOME/db directory
and restart amavisd

At least one of the above solution should work.
