Please stop sharing your stupidity here! Running an anti-virus in Win is the only way to go and even that is not guaranteed protection. It's not about knowing what you are doing (and you've already proved you don't) it's just you have been lucky all this time. If you just plug your pen drive on an infected system with Windows it'll pass the virus to your pen drive. And YES, your Win WILL autorun the virus when you plug your pen drive in it, doesn't matter what options you have selected on it. Fact, Windows is full of holes for viruses.
As for running as root to use VirtualBox. no comments there, this blog itself explains how to use VB as normal user.
Stop posting man, you're just too f** stupid.
