This does not look like multiple times per seond.
If I 'kill -9 `pidif clamd`' then it does not come back. The service
file does not say to restart it:

|systemctl show clamav-daemon.service | grep Restart
|Restart=no
|RestartUSec=100ms

So it remains offs. However we have socket activation for clamd. So
assuming that you have a mailserver poking at the socket then it will
bring clamd back from the death.

I have no idea how to limit / disable the restart or make it
configurable in this case. Maybe someone with systemfoo has an idea :)
