Subject: [PATCH 1/1] clamav-unofficial-sigs.sh: disable running as root.

The only way I'm going to let this be installed on my machine is if
it never runs as root. The shit that it does is insane (a priori)
and also implemented insecurely. There's no good reason to run the
script as root on Gentoo anyway. A cron job is provided for you,
or you can use "su -s /bin/bash -c ... clamav" to run it as the
clamav user.
