A: The answer is this: LocalSocket /var/spool/amavisd/clamd.sock not being equal to this: ["CONTSCAN {}\n", "/var/run/clamav/clamd.sock"],, you need to decide which one you want to use, then set both programs to use it.

A: At the very beginning there is no clamd.sock file inside the /var/spool/amavisd/ directory. If you change the path of LocalSocket /var/spool/amavisd/clamd.sock or ["CONTSCAN {}\n","/var/run/clamav/clamd.sock"] as above answer it will give an error,
[root@hostname ~]# /etc/init.d/clamd.amavisd restart
Starting clamd.amavisd: ERROR: LOCAL: Socket file /var/run/clamav/clamd.sock is in use by another process.
                                                           [FAILED]
[root@hostname ~]#

No need to change as above. I had the same problem. So I just start clamd.amavisd service. Then it works fine. The problen is we are not start clamd.amavisd service we start only clamd service.
[root@hostname ~]# /etc/init.d/clamd.amavisd start
Starting clamd.amavisd:                                    [  OK  ]
[root@hostname ~]#

Then it will create clamd.sock file automatically inside the /var/spool/amavisd/.

No it doesn't - you will get a permission denied error if you do that.
