Hello,

Thank you for your email.  As a result of events documented in places here:
https://lists.clamav.net/pipermail/clamav-users/2021-March/010577.html
and
https://lists.clamav.net/pipermail/clamav-users/2021-March/010543.html

We’ve been forced to take emergency measures to protect the ClamAV environment.

Please Immediately switch to using Freshclam or https://github.com/micahsnyder/cvdupdate to update your AV definitions. If you are using Qnap or ClamWin, it’s likely that you are using a version of ClamAV that has been EOL’ed: https://blog.clamav.net/2021/02/clamav-eol-versions-prior-to-0100.html

Sorry for the inconvenience, but we are currently in emergency mode and have to make several drastic changes over the last several days.

 Hi Francois,

From what I understand ClamAV have tightened their download policy. Cloudflare is now more restrictive.

You are able to use their freshclam client to download updates, but if you try and download directly via methods such as wget, curl… Basically any scripted method you will receive the 403 response along with an error code in the response. As you said via the browser is working fine.

Kind Regards
