OK, as far as I can see, the issue comes from the setmbr.exe that is
contained in the iso for writing the KolibriOS to an USB stick.
According to http://board.kolibrios.org/viewtopic.php?t=2295 the report
from Avira is a false positive (likely caused because the program tries
to write to the MBR - which is also what some viruses / trojans are doing).

Anyway, since these Windows tools are not required for running KolibriOS
in a VM, I've now removed them from the iso image and uploaded a new
version to avoid future confusion:

 http://www.qemu-advent-calendar.org/2016/download/day09-v2.tar.xz

If you've got some spare minutes, it would be great if you could give
that new version another try to see whether the warning from Avira is
now properly gone (I don't have a Windows here to test this on my own).

 Thanks,
