Comment 3 for bug 1628275

There is already a bug filed with debian.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=822444

Seems that the problems is due to switching to systemd and false settings within the start of clamav.

From the bug report above:

/lib/systemd/system/clamav-daemon.service

Change ExecStart to:
ExecStart=/usr/sbin/clamd -c /etc/clamav/clamd.conf --foreground=true

Add:
User=clamav
Group=clamav

Bug on debian is closed an a fixed clamav-package should be available! But also to ubuntu?
