Windows Server 2008 reached end of mainstream support long ago and extended support ended on January 14, 2020. That affects antivirus considerations because the OS no longer receives security updates, so protecting servers running it requires extra caution.

Microsoft offers paid ESUs for Server 2008 and 2008 R2, but only through specific programs (Volume Licensing, or via Azure Stack).
