  1. You want `apt install clamav` instead of `apt upgrade clamav`. `apt upgrade` installs all available updates for all packages installed on the system, and the `clamav` after it has no effect.

    A more complete command would be `apt install clamav clamav-base clamav-freshclam`, that will also update related packages.

    Thanks for the blog post! Somehow I didn’t think to update clamav to fix the problem.

    1. Thanks for comment! well we did it successfully with ‘apt upgrade’ on several debian 10, after that freshclam will do updates again, note. apt install triggers the upgrade for an already installed package. note. we haven’t done it on ubuntu yet!
