ports (tcp 139) how to close

[GazzyD]

I'm not entirely sure if I'm in the right area for this question so I
apologise. I'm running Vista Home Premium and apart from my AV and 4 AS
programs, I run a few other good free security checks. One of them is
MyNetWatchman which today picked up an "unknown file" and after a bit of
investigation I found that it related to TCP/139 and the status of this port
was "listening". I have also read that this port is classed as "the single
most dangerous port on the internet" due to the traffic that passes through
it and hackers. Could anyone tell me how to "close" port 139 ? Thanks in
advance

Have you turned off the built-in firewall? Unless you have you have nothing
to worry about. It would block traffic to that port.

Port 139 is NetBIOS (computer name) based Windows Networking. In other
words, it is what clients use when accessing your computer as a server. It is
obviously not needed on all computers, but the firewall would block it unless
you modify the firewall settings so you should have nothing to worry about.

OK, thanks Jesper. I've not turned the firewall off and your reply has put my
mind at ease - thanks again
