Hello. I saw the other threads here about people who ran GRC Shields Up and found that port 554 was open.
When I was using Windows Firewall, I was completely Stealth according to GRC's site. I decided to install Norton Internet Security 2011, thinking this would make me more secure. I reran the GRC test and it showed my port 554 was now open.
Why does the Norton firewall open up this port? And more importanty, how can I Stealth this port? I did not understand the answers on this forum instructing to shut off Windows Media Player.
I am starting to think maybe I would be better off going back to the Windows Firewall. :(
