[clamav-users] Malformed database issue

Hello and good afternoon,

Yessterday on a Centos 6.10 server I ran the software updater application which indicated 134
packages needed to be updated, one of which was Clamav.

The updater ran fine and the machine was rebooted. Upon reboot Clamav failed to run. This was due
to the deprecated option "AllowSupplementaryGroups" being enabled. Once I disabled this Clamav
would run, but I also was receiving a second error, which I have not been able to resolve.

It occurs when Freshclam queries the server for updated virus database files. I have enabled
logging for libclamav when freshclam runs to provide additional details.

Update failed. Your network may be down or none of the mirrors listed in /etc/freshclam.conf is
working. Check https://www.clamav.net/documents/official-mirror-faq for possible reasons.

NOTE: I just copied of the five tries for updating, they all show saw situation.

I am pointing to db.us.clamav.net as the country code.

Any idea how to resolve this?
