You can snatch alsorts of information about a system from it's open ports. I have not used www.securityspace.com but I guess they have a database of known trojan ports, here's one: http://www.simovits.com/nyheter9902.html. For instance port 20034 is a known port for Netbus Pro 2, http://www.davidm.8m.com/netbus.html . It is similar to Back Orifice and runs on NT, if you're OS is not NT, it's probably a false alarm. If I were you I would find out which applications are listening on what ports and then decide whether you require them or not.
