Much more likely that your A/V software is doing e-mail scanning "cloaked".

And then scanned some computers on my subnet and then on other subnets. They all showed ports 25 and 110 open. Since I never got false results from my languard beta in years, I immediately suspected that all of these computers were infected with some type of spam bot. I picked out one machine and installed every type of free port monitor on it that I could find. All results showed that that the ports 25 and 110 are not open. I think our firewall guys, they just started installing and learning about firewalls, have it setup so that the firewall intercepts any telnet session to 25 or 110 and gives it a window. Is this possible? I have not tried moving my languard beta scanner outside the firewall to test the ports. On another note, a few years ago, I used the languard scanner to look for a trojan that was infecting computers and found a port open on a linux machine that corresponded to the port the trojan was infecting. Come to find out, the linux machine was using some type of proprietary software that used the same port as the trojan. We said, eh ok, you are clean, you can get back on the network.

My guess would be Languard see the port number and immediately associates with Trojan, without checking to see if it is udp or tcp.

Hey, if you have TCPView running when you also run a Nessus scan on same system…now that’s funny right there… Nessus shows nothing, TCPView shows nothing, NETSTAT shows nothing…only Languard shows something at those ports… Dave From: Michael B.

The "o" gives you the process owning the port, which you can use TaskList or Task Manager to find. If it isn't in the list - you've been pwned.

Now I have something, or not…GFI Languard scanned a machine that says I have two KiLo ports open (6666,6667). TCPView shows nothing in that range….comments?
