Been doing some thinking about MITB

For those that are not aware of what MITB is. It's basically a hidden browser trojan that could capture and or change online financial transactions without your knowledge. I have been reading about this and it doesn't seem there is a lot that can be done unless your bank offers out of band authentication. Which means they contact you in some way outside of your pc to authenticate transactions. I realize that once your infected then there is really no way to protect yourself. I was reading this article and I think it's a good idea. What do you guys think? Increasing your banking security by using a dedicated browser (Preston Hunt)
