All,

Yesterday, Sep-30 2025, CDN rules were updated to enforce the end of life r=
ules and block ClamAV 0.103 from signature updates.

As you may be aware from previous announcements, ClamAV 0.103 is now past e=
nd of life for signature database updates. Specifically:

  *
ClamAV 0.103 exceeded end of life for security patch support on Sep-14 2024=
.
  *
ClamAV 0.103 exceeded end of life for signature database updates as of Sep-=
14 2025.

If you are affected, you will have to upgrade to ClamAV 1.0 LTS or newer to=
 continue to download signatures from database.clamav.net.
If your operating system does not support a newer version of ClamAV, you ma=
y need to upgrade your operating system version, use the ClamAV team instal=
l packages, or else build and install ClamAV from source.
