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. _______________________________________________ Manage your clamav-users mailing list subscription / unsubscribe: https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/Cisco-Talos/clamav-documentation https://docs.clamav.net/#mailing-lists-and-chat
