If you are seeing this in your logs you are affected by this bug:

The so far this bug is confirmed and reported only in Ubuntu 16.04 LTS, the fix is easy. If you have installed this software before December 1st 2017, the patch is trivial, just run this on console as root:

chmod -R 775 /var/lib/amavis/tmp

That's all, restart your amavis/clamav daemons or the entire PC and you are done.

From that date the fix is covered on the install process.
