I got to thinking: surely that name makes no logical sense? Does it refer to malicious forces in your residence, or what? In Japan, the series goes by the more logical title of "Biohazard", which I prefer, because at least it undoubtably conforms to the basic rules of the English language, which is ironic, considering that only a non-English speaking nation uses the name. Anyway, perhaps a helpful fanboy can assist me on this one, eh?
