On a puppetrun I get the following message when the ClamAV Daemon wants to start
May 5 14:01:43 mailscan-02 systemd[1]: Started Clam AntiVirus userspace daemon.
May 5 14:01:44 mailscan-02 clamd[18391]: ERROR: Incorrect argument format for option AlgorithmicDetection
May 5 14:01:44 mailscan-02 clamd[18391]: ERROR: Can't open/parse the config file /etc/clamav/clamd.conf
A default config from the ClamAV installation works well.
