It's painfully slow to run freshclam, but clamav-daemon won't start without it:
$ sudo service clamav-daemon start
* Clamav signatures not found in /var/lib/clamav
* Please retrieve them using freshclam
* Then run '/etc/init.d/clamav-daemon start'
Can I get clamav-daemon to ignore it so each server don't have to run a 10-30 minute update on first deploy?
