Making clamd Run Automatically

Whoops. Back when I was installing ClamAV, I started clamd running so that I could test the virus checker. Yesterday, I rebooted the PC.

Obviously, clamd didn’t restart with the PC, so I was getting X-Qmail-Scanner-1.21:[flimsy10800482284701388] clamdscan: corrupt or unknown clamd scanner error or memory/resource/perms problem - exit status 2 messages in my log and qq temporary failure messages in my email client.

The fix is to steal the startup script for the clamav-daemon Debian package, from http://packages.debian.org/unstable/utils/clamav-daemon.
