Comment 16 for bug 2003864

Looking at the upstream repo for clamav I suspect the following commit is required to be backported to clamav in lunar https://github.com/Cisco-Talos/clamav/commit/375ecf678c714623e6fb5c0119d1bec98dc700dd - or that a merge is done of clamav-1.0.0+dfsg-6 to lunar.

The merge is likely the best option I suspect.
