When I run the online Symantec Security Check it shows an open port. It
says, "Security Status: At Risk! You are vulnerable to at least one form of
security threat." The details show all ports Stealth except for Port 4567.
It shows that one open. How do I close this port?

Thanks for the reply. I used TCPview and it didn't show port 4567. Does
TCPview show an open port even if no one is listening in on it? Could it be
that it is open and vulnerable even if it isn't being used? Is file name the
name of the port or is it a program that opens that port? I can't find any
program named filename or file name. I've been trying for about 3 weeks now
to find a way to close this port.

Correction. That should have been file nail or filenail.

I have 3 computers networked together. I am connected through a router. One
computer is wireless and the other 2 are connected with Ethernet cables. All
3 computers show the same open port when I run the Security Check. I
suspected that it might be the router so I had my ISP check the router but
they didnâ??t find anything. It could still be the router. My ISP is Verizon
FIOS. 2 computer operating systems are XP SP2 and one is Win98SE.

When I run TCPview I donâ??t see Port 4567. The only time I see this open is
when I run the Symantec online Security Check.

I've run TCPview on all 3 computers. I don't see Port 4567 on any of them.
It's only the Symantec online Security Check that shows this port open and it
shows it open on all 3 computers.

Are you talking about online scanners for the Security Check or to see what
else is running on my computer? I don't know of any other Security Checks.
Do you have any suggestions?

I've tried Fport to see if it would find port 4567 but it didn't. I only
did that on two of the computers though. Fport wouldn't run on the win98se
computer.

I ran the Advanced Port Scanner from pcflank and it showed port 4567 open. I
checked a range of ports from 4560 to 4570. 4567 was the only one open.

I checked the Port Forwarding on my router and it's not configured to
forward any ports.

Is there any way to determine exactly where this is coming from? I've
talked to my ISP but all they did was check my router.

I couldn't find anything that looked like my router was configured for
configuration access from the outside.

When the Security Check scan is running it shows the IP address of my
router. That's the same address that shows up when I am on any websites.
