SME 9.2, followed instructions under the wiki entry at
https://wiki.contribs.org/Clamav_unofficial_sigs (I did create an account).
I'm getting the following error from the cron job:
Subject: Cron <root@mail> [ -x /usr/sbin/clamav-unofficial-sigs.sh ] && /bin/bash /usr/sbin/clamav-unofficial-sigs.sh
======================================================================
ERROR: clam database directory (clam_dbs) not writable /var/lib/clamav
======================================================================
I could not find this directory /var/lib/clamav, only /var/lib/clamav-unofficial-sigs/ exists, with clam-update:clam-update permissions.
