a possible solution to run avg is:
first install avg with your preferred linux to a local machine as root.
sh avg85flx-r855-a3656.i386.shthis installs avg to /opt/avg/avg8/
next run
cd /opt/avg
tar cfz avg.tgz avg8
this creates the file /opt/avg/avg.tgz. copy this file to the pluspacks (or ploplinux/opt/ for ploplinux 4.1 and higher) directory.
now create a script maybe "useavg" to prepare avg during ploplinux startup
#!/bin/sh
echo EXPORT AVG8INSTDIR=/avg8 >> /root/.bash_profile
echo EXPORT PATH=$PATH:/avg8/bin >> /root/.bash_profile
tar xfz /media/pluspacks/avg.tgz -C /
echo /avg8/lib >> /etc/ld.so.conf
ldconfig
run the useavg script with runme.sh (or rc.local for ploplinux 4.1 and higher)
when i forgot nothing, then you are able to use avg

i think i add this to the next release
this solution copies avg to the ram, when you don't want to waste ram space with this, then its also possible to use avg on a storage or network drive
