Cannot switch to 'Local Server Scanner'

A new install with CentOS 7.

In Virtualmin > Email Settings > Spam and Virus Scanning - when changing the 'Virus Scanning Program' to Local Server Scanner I get the following error:

 The selected virus scanning command does not work :  

 ERROR: Could not connect to clamd on LocalSocket /var/run/clamd.scan/clamd.sock: No such file or directory  

 ----------- SCAN SUMMARY -----------  
 Infected files: 0  
 Time: 0.000 sec (0 m 0 s)

The server has been up and running for about a week and I have had this issue from day one.

You might double-check if Webmin in general (recently) has a problem with starting/stopping services, by going to Webmin's "System / Bootup and Shutdown" module, and see if you can start/stop ClamAV and Spamassassin there.

Current status of clamd = 'not running'. Starting clamd service I get:

This is with 'Standalone Scanner' set as the Virus Scanning Program in Virtualmin

Having tried a few combinations of start/stops/enable/disable/boot/reboot, what it boils down to is

if ClamAV Server is running and the system then rebooted then Clam shows the errors in the first post and CPU usage is consistently high. So I then have to manually disable and then enable ClamAV Server - system then works correctly.

I just have to Disable/Enable each time I reboot.
