[Earth]

It's just impossible lol, no virus can provide oxygen and glucose to the muscles after death so they wouldn't even be able to move, Secondly, Even if IF there was a virus that let the muscles work after death, they would be slow and easy to kill, but would detriorate anyway over time so it wouldn't even be an apocalypse.

Who said zombies have to be dead? there is known viruses that cause zombie like actions/reactions to a living human.

Even bath salts does it but its not permanent.

It would not be like the walking dead or anything like that.
