avgd()
  AVG daemon realscanner.
  
  This scanners is a realscanner, which can be used to scan
  for viruses. It uses AVGd (a deamonized linux version of AVG7).
  
  Usage: avgd(params='', connto=('localhost', 54322), chroot='')
  
  Where: params is a string which defines command line parameters,
           like -arc, -heur, -rt, ... see man page for avgscan
           This option is not accepted by AVG8+, so it defaults to "".
         connto is a tuple of host,port of avgd,
           by default ('localhost', 54322)
         chroot is an string in which sagator is running, if avgd
           is not running in this chroot. By default chroot='', so your
           avgscand should run inside sagator's chroot.
  
  To start AVGd in chroot, move all neccessary files into your chroot,
  and change following line in init.d/avgd from:
    daemon $AVG_HOME/avgscan -d
  to:
    daemon chroot /var/spool/vscan $AVG_HOME/avgscan -d
  or similiar.
