ClamAV doesn't seem to work

[Emrion]

I have pfSense 2.4.4 and I enabled ClamAV on Squid proxy. All services are running. I get this error on freshclam table log: Can't connect to clamd through /var/run/clamav/clamd.sock: No such file or directory. (The file in question exists yet).

The problem is: I can download eicar file without any blocking. So it's not working at all.
