this looks like the DNS lookups are not vailable, no matter what your check
says.

there seems to be no issue further.

do you use clamav that comes with ubuntu?

try running:

% ls -ld /etc/systemd/system/multi-user.target.wants/clamav-freshclam.service /lib/systemd/system/clamav-freshclam.service
lrwxrwxrwx 1 root root 44 Jun 23 2018 /etc/systemd/system/multi-user.target.wants/clamav-freshclam.service -> /lib/systemd/system/clamav-freshclam.service
-rw-r--r-- 1 root root 412 Aug 21 21:28 /lib/systemd/system/clamav-freshclam.service

the clamav-freshclam.service should contain the line
"After=network-online.target"

it would appear your calling your script before the network and dns are

What if your use of the 'host' command returns NXDOMAIN in you script .

Hi,
> What if your use of the 'host' command returns NXDOMAIN in you script
this can't usualy be, this command returns the descriptive txt for the current remote version of libaries.
For example, the current value (inside the curly braces): { current.cvd.clamav.net descriptive text "0.103.8:62:26814:1676572140:1:90:49192:333" }
