  DatabaseMirror foo.bar.com
  DatabaseMirror bar.baz.com
  PrivateMirror private.mirror.local
  Bytecode false
  ...

to:

  ...
  DatabaseMirror db.local.clamav.net

Example Playbook

Here's how to use it in a playbook:

- hosts: all
  become: true
  become_method: sudo
  tasks:
    - name: Install ClamAV and a cron job to run automated AV scans
      ansible.builtin.include_role:
        name: clamav

Cron job output

The log of the last scan is accessible at: /var/log/clamav/lastscan.log

If a detection occurs the file /var/log/clamav/last_detection will be touched. Its modification time represents the time of the last detection.
