Help with config of clamd.conf to support ClamAV.

I have added the ClamAV plugin to my claws-mail configuration.  I know
that clamscan works with the Slackware64 14.2 installation.  But I
continue to get the error message from claws-mail that it can not ping
Clamd.  Checking the config under
Configuration>Preferences>Plugins>ClamAV 
I don't see anything incorrect with the file location or tmp setting,
per clamd.conf.  
Clamd.conf specifies 
LocalSocketGroup clamav 
and
LocalSocketMode 660 
and TCP Port address is not set.

Are there other settings I need to use in clamd.conf to stop ClamAV
plugin error message?  

Thanks, BrianA_MN
