Issue with CLAMAV

I do not understand how, but ClamAV is not anymore listening on port 3310

$ netstat -lnp | grep -E “(clam|3310)”
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
unix 2 [ ACC ] STREAM LISTENING 22107 - /run/clamav/clamd.ctl

Although, it was well working in the past…

For this configuration, I added port in freshclam.conf

sudo vi /etc/clamav/freshclam.conf

TCPSocket 3310

I noticed my config was removed from freshclam.conf (maybe due to an update ?) and now even by added again TPCSocket 3310 in freshclam.conf, it does'nt work. ClamAV is not listening on port 3310.

I would like to add that my NC instance is a SNAP version under Ubuntu with activated updates.
But ClamAV is a systemd service installed on my local Ubuntu.

So I do not know how to restore communication between them.

May you Help me ?

Best Regards
