Beware originates from the Old English "be-" (meaning about or around) and "warian" (meaning to guard or to be on guard). The word means to be on guard about something, indicating caution or alertness.
Think of being 'around' ('be-') something that you need to 'guard' ('warian') against — that's why you should beware.
