Open & Insecure Port

Have just had my computer security checked @ Hackerwatch.org/probe.
It reported one port as ‘open and unsecure’ - 139 (netbios), stating that this was ‘very dangerous’ and that I should check my firewall configuration.

Has anyone any knowledge of this site and is it to be relied on ?
Should this port be closed and, if so, how is this done ?

Greetings,
Do you use a router? If yes, then it’ll test your router and not CFP. CFP should stealth all ports with default rules.
