Vista - Hole in my bucket

I recently ran a couple firewall tests, shields up and auditmypc etc. They're both coming up with a port that's open. I think they called it Tram. It says this port is commonly used for trojans. But my biggest concern is that it is open and I would like to shut it. I have searched my firewall completely for port control options and cannot find the solution anywhere. It also said that my computer responded to Ping (ICMP Echo) Requests. Buy my firewall says that this is blocked, so I do not know how it is still responding. If anyone has had any similar experiences with these firewall test sites, because I don't know if it is my computer or the sites themselves. Please feel free to envelope me in the answer to my frustration.
