There is also a log written there.

clams.conf:

It is unclear what file “Can’t be opened” (clamd.log doesn’t say, I was guessing the socket because it wasn’t there)

Directory for the socket is owned by _clamav so that should not be a problem.

So, clamd is running.
Hmm, suddenly the socket is there now (after a second launch attempt)

My guess is this: clamd did not want to start untill I had at least once ran freshclam. AFter that, there was a database and it could start. Does that make sense?
