Present pkg version is stuck back at clamav-0.99.4nb3:
Currently, every version from ClamAV 0.99 and down, including all patch versions, are unsupported, and are actively blocked from downloading new updates.
Apologies that I didn't get to this at the time. 2018Q4 has been EOL for a while, and newer LTS and trunk have more recent releases. Will be looking to get the latest in prior to 2022Q4 being released.
Latest stable version of clamav is 0.103.1
Present pkg version is stuck back at clamav-0.99.4nb3:
