I'm all about Qubes but can't install it on my ghetto DN computer, can VirtualBox on Windows be trusted for small potatoes activities? Would VBox on Ubuntu be a better bet? I would think that a fulldisk encrypted windows, running VBox VM, running whonix might be secure "enough" but I implicitly distrust windows...how sketch 1-10?
there is no use in doing a VM on windows, how would this help at all when your main system is compromised?
