Query about sharing/privacy

[zalex]

I just noticed someone's computer name (I think it's my neighbours) under the "Shared" section in Finder. Is this person using my wifi? Can I block them?
Thanks in advance.

I think it does mean that's he's using your wifi! I don't see any other way he would show up under shared.

Yes. It's probably because you don't have a router password or it's the default one which is usually "admin."

To prevent people from leeching off your internet I suggest reading guides about home network security such as this one:
