Hi Gordon,

and you remained on Jessie, correct?

So, could this be a systemd issue? The bottom line is that clamav is now totally broken which has subsequently broken exim's virus checking as well. freshclam reports the following in /var/log/freshclam.log:

You should have /run which is a tmpfs:
|$ mount|grep "run "
|tmpfs on /run type tmpfs (rw,nosuid,relatime,size=1607508k,mode=755)

and /var/run should be a symlink:

|$ ls -l /var/ | grep "run "
|lrwxrwxrwx  1 root root      4 Aug  3  2013 run -> /run

and since you run systemd there should be two service files:
|# systemctl status clamav-daemon.socket

If you read the .socket file then you will see that one creates the
socket and the .service file depends on it. Uppon start, systemd passes
the socket to clamd then. I *assume* that the socket part is not started
for some reason on your machines.
