Can there be a virus that can turn humans into phsyical zombies or something like that?...

Well for humans, most people think a rabies virus could do it (if it mutates fast). The problem is, rabies isn't really contagious enough to start a pandemic per se, but it would basically turn you into a "zombie". There are also a ton of other rare viruses and fungi that could trigger that, but they aren't proven on humans.
