Ralf, thank you for all the information. I've been messing with this
most all of the day and I'm still confused because even though I have
this for the clamd.sock path

LocalSocket /var/lib/clamav/clamd.socket

And I've created the file as per the instructions you gave

chris at localhost:/var/lib/clamav$ ls -l *.socket
-rw-r--r-- 1 clamav clamav 0 Aug 21 17:05 clamd.socket

I even made sure the socket name and path were correct in the
/mail/spamassassin/clamav.pm 

# our $CLAMD_SOCK = 3310;               # for TCP-based usage
our $CLAMD_SOCK = "/var/lib/clamav/clamd.socket";

I started the daemon

chris at localhost:/var$ sudo systemctl start clamav-daemon.service

then checked the status

chris at localhost:/var$ systemctl status clamav-daemon.service

So, after going through all of this multiple times, too many to count,
checking permissions on files and folders, comparing with my 14.04
backup I still get

X-spam-virus: Error (Cannot connect to unix socket
'/var/run/clamav/clamd.socket': connect: Permission denied)

There is a clamd.socket file in /var/run/clamav

chris at localhost:/var/run/clamav$ ls -l *.socket
-rw-r--r-- 1 clamav clamav 0 Aug 21 09:04 clamd.socket

And also in /run/clamav

chris at localhost:/run/clamav$ ls -l *.socket
-rw-r--r-- 1 clamav clamav 0 Aug 21 09:04 clamd.socket

Shouldn't a socket file have an 's' as the first character such as this

srw-rw-rw-  1 root   root     0 Aug 18 15:45 snapd.socket

So, and I may be repeating myself, why does the daemon keep looking for
the socket file in /var/run/clamav when I state in the clamd.conf file
that it is in /var/lib/clamav?

Apologies for the long message and hopefully I didn't repeat myself too
many times and hopefully I've explained everything that I'm confused
about.
