How to stealth port 1030?

[alegator]

I went to this site:
https://www.grc.com/x/ne.dll?bh0bkyd2
and tested all ports for stealth status. All ports came up stealth except port 1030 which showed as closed, as shown in the snapshot below. Is this a security threat to my PC? I'm running Norton Internet Security 2008. I tried turning Windows Firewall on in conjunction with NIS2008 and all ports become stealth, but NIS2008 alone leaves 1030 closed. I know that running two firewalls simultaneously is not recommended, so how can I fix this? Thanks.

a "closed" port is not a security concern. it's "visible" to other computers but not accessible. it's not an "open" port, that would be a problem.

"closed" is not the same as "stealth". In stealth mode the port is not anly inaccessible but also invisible. In closed mode the port is inaccessible but it is detected.

Drop Norton, install something better.

You didn't read far enough on the GRC website. He explains the threat levels and what you can do to get all ports into stealth mode.
