service? Not systemctl? Do you use SystemV oder SystemD?

/run/clamav should be created by the init script and owned by by $User.
In case of systemd it is created by clamav-daemon.socket file.

if run under systemd the PidFile is not required.

If you use it only localy then I would recommend the unix socket. It can
be used clamdscan not to confuse with clamscan.
To get TCP working, you would have to extend
/etc/systemd/system/clamav-daemon.socket.d/extend.conf if you use
systemd. The debconf template does this for you.
