Are new viruses spontaneously mutated? In one million years will humans be immune to all viruses on Earth?

(If Earth is still habitable in one million years)

Long story short, yes, they are. Since viruses reproduce so quickly and stuff is always trying to kill them, they evolve on a much more rapid scale. Otherwise we would have been immune a long time ago. It's also why it's so hard to find suitable cures for some viruses, because they can become resistant so quickly.
