A few days ago I activated the antivirus on my encrypted ReadyNAS 628 under OS 6.10.3. This resulted in a never ending series of errors in the logs:
System: Antivirus scanner definition file update failed due to download failure. Check your Internet connection.
Based on previous threads I used SSH to see what was going on.
I ran
freshclam
and got

(this repeats several times)
Looking in /var/lib/clamav there was a .tmp file and mirrors.dat but no main.cvd file.
Based on some reading I manually downloaded and installed the database files:
daily.cvd
bytecode.cvd
main.cvd
I downloaded those three files, moved them to /var/lib/clamav, changed their ownership to clamav:clamav, and changed their permissions (chmod 644)
Now when I run
freshclam -v
I get this somewhat better looking result:
Current working dir is /var/lib/clamav

main.cvd version from DNS: 59
main.cvd is up to date (version: 59, sigs: 4564902, f-level: 60, builder: sigmgr)
daily.cvd version from DNS: 25844
daily.cvd is up to date (version: 25844, sigs: 2622498, f-level: 63, builder: raynman)
bytecode.cvd version from DNS: 331
bytecode.cvd is up to date (version: 331, sigs: 94, f-level: 63, builder: anvilleg)
So, if I read this correctly, my executable is out of date but my databases now are acceptable.
1) Should I leave well enough alone and call it a win?
2) What's the recommended way to get clamav up to date?
3) What went wrong in the first place on what is basically a new system?

A day and a reboot later, the log has not accumulated any more of the messages
System: Antivirus scanner definition file update failed due to download failure. Check your Internet connection.
After I rebooted, there was one anomaly in FrontView/System/Overview. It showed Antivirus as green but with a little status message
Updating virus library. Refresh to update status
next to the green circle ( • ).
A few minutes ago I get the alarm (yellow message)
Antivirus scanner definition file was updated to 59.25845
I pressed the Refresh button on the FrontView/System page and Antivirus now says
Jun 16, 2020 09:01:35 AM
instead of "Updating virus library. Refresh to update status"
I guess this means everything is working properly again, but I have no idea why I had to manually install the antivirus libraries to get clamav back on the rails.
