I found No way to kill VirtualBox processes, even windows restart was not successful and I had to hardware reset the PC. This was the first time I found an issue with VirtualBox (also the first time I had to HW reset the PC that is really stable). I roll back to release 4.3.12 that was and still is perfectly stable. Also release 4.3.14 was working but I decided to skip it because of the conflict with antivirus (not seen on my PC with Avast but found on my notebook with Symantec EP).
