Newbie question,

I have Norton 2003 firewall/viri scan....always updated. a linksys router. the cleaner ....of which seem to be configured correctly.

Norton allerted me that there was a intrusion attempt made to port 3000 something (i forget).
And that it had blocked it . The culprit was the subseven trojan horse.

I then checked my registry to see if entries were made . (run services)

I checked netstat....nothing.....and did a virus scan.

I didn`t think that i had opened any mail with the trojan in it (subseven).

Anyways i guess my question is what happened here was his an attempt to deploy the subseven server on my machine by someone? and if that`s the case it would seem this person knows what they are doing? How did they get by my router? any help would be great....

Thanks in advance.
