    Buy and setup a decent router - eg. Netgear DG834...easy to setup and
    it will be completely under your control.

    Set ZoneAlarm to trusted... the router will block filesharing to the
    Internet(unless you configure the router to allow it). The router has
    4 network ports so you can use as your network hub/switch.
