Check if clamd is really listening on this Unix-Socket. Maybe it is configured
to listen on an inet-socket. Have a look in /etc/clamav.conf.

No, but it does not matter in this case. You will only fall in this pitfall,
if you submit Mails via commandline (sendmail,mail,..).

Change in main.cf:
content_filter = smtp:[127.0.0.1]:10024

You configured clamav to listen on an inet-socket. Amavisd looks for a
unix-socket.
