Not clear to me what you mean by "delete the BGP configuration". I'm
sure if you just do "delete protocols bgp" you don't get bgp running
I would start by removing the "allow 0/0" statement. It means that the
router is willing to establish a peering session with any box that
sends it a connection request. This is probably what is confusing you.

An incoming BGP session is accepted if:
a) a static configured neighbor is in the config.
b) an allow statment is found that includes the address in question.
I'd bet on b) in this case.
