I've used a Linux VM for web browsing in the past. But knowledge is the best defense, IMO. I usually only run MSE for system security. Then again, I manage a Windows network with ~120 users, so they provide a fertile testing ground for learning how to best avoid a malware infection, as well as what steps to take when a machine becomes infected.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
