Computer Security - Port 80 OPEN!!!!!

Default Port 80 OPEN!!!!!


Hi all security experts!
I have a Win98SE machine running Kerio Personal Firewall 2.1.5 and blackICE
IDS. I am behind a Belkin Gateway Router with NAT and firewall enabled.
When I run a Shields UP 'common ports scan', port 80 is found to be open!
A few months ago, when I last checked, all ports were stealthed.
A virus/trojan scan with AVP 3.5, Sophos AV 3.72, Inoculate IT 4.5, eSafe
AV, F-Prot for DOS, TDS-3, The Cleaner and Trend Housecall all show
negative results.
Inspection of all running processes, msconfig startup, and autoexec.bat
contents show nothing suspicious.
I have uninstalled personal web server.
The Kerio Firewall Status and ‘netstat –an’ show no suspicious connections.
(see below)

UDP 192.168.2.2:138 *:*

Remote administration and DMZ is disabled on my router.

A spyware check with AdAware and SpyBot S&D (all updated) shows no spyware
infestation.

What could be causing port 80 to be open, and how could I stealth it?

Thanks in advance.

Richard

It's probably port 80 on your router (remote admin).

When you run external scans against yourself you are running them against
your router (Your public IP address)

Not against your actual PC.

I can confirm your port 80 is showing as open but I'm unable to connect to
it.

most home routers have web administration which means they use
port 80 which is the default web server port.

On some you can specify that port 80 is only open to your local
network. This is generally a good idea and prevents anyone from
the internet administering your router.

It may be that that is the way yours is already configured if an
external scan does not show the port as being open.

Connect to it and see what it says. Then read your router manual
carefully.

What worrys me is that last time when i ran Shields UP (a few months ago)
all ports were stealthed.

Remote/web administration is disabled on my router, and Shields UP still
reports port80 as open.
Could someone have hacked into my router and changed the settings so it
looks to me that remote admin is disabled, but really it is enabled?
The router settings are protected by a non-default password, and i have
never enabled remote administation before.
