Scenario

ClamAv Antivirus had stopped download manually download virus database and suggest to do online updating since March, 2021.

Somehow the download links for virus database are still available so you can update manually.

ClamAV didn't provide the links officially.

Please read officially recommendation from ClamAV.

Workaround

1.Download 3 virus database files from links below:

http://database.clamav.net/daily.cvd

http://database.clamav.net/main.cvd

http://database.clamav.net/bytecode.cvd

Links May Not Be Stable

You might not able to access the links once ClamAV server detects too many accessing and get you blocked.
Try with other WAN IP to prevent block.

2.Go to Control Panel > Applications > Antivirus > Browse to choose one file each time then press Import

3.Update process completed after you imported 3 files.
