When you have a problem like this it's good to carefully read down
through the error messages provided as you'll often find hints there.

As shown in your log, the first couple of attempts failed due to dns
name resolution failures, then it worked on its retry.

You will need to use a tool like dig to work through why your machine
is having these lookup failures. It could be latency in the response
from the nameservers you have configured or a problem is how [or
what] you have configured [as] the nameservers that this machine is
using. It is possible that there is an issue with the nameservers on
the clamav.net side, but that seems less likely as there would
probably be more general reporting of a problem if that were the case.

Hi all!

I've just ran freshclam again, and it worked.
I'll keep an eye on it.

Regards,
Alex
