Description of problem:
If the "NotifyClamd" option is specified in /etc/freshclam.conf like so:

# Send the RELOAD command to clamd.
# Default: no
NotifyClamd /etc/clamd.d/amavisd.conf

Then when freshclam downloads new virus signatures it tells clamd to reload the signature database via /var/spool/amavisd/clamd.sock.  However, SELinux prevents it from going into the directory /var/spool/amavisd:
############################

SELinux is preventing freshclam from search access on the directory amavisd.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that freshclam should be allowed search access on the amavisd directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep freshclam /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
