Dear Doctor
I use Norton NPF and AV 2003, so I believe yours and mine will be similar in usage.
First, I suggest that you get PeerGuardian V2 Beta5 and install it. This will keep all sorts of computer, gov, education and Uncle Tom cobbly agencies from accessing your computer via port 6346, see the following:

When you have done this, run your virus scanner (which must be up to date) to insure that you have no Trojans or viruses on your PC. I would also run my anti-spyware apps as well, i.e. Spybot, Ad-Aware and MS Anti-Spyware.
When you are sure that your PC is clean, read the Norton message, which indicate the type of connection, e.g. someone using the port associated with Back Orafice, etc.
Now, if it is a connection that is commonly associated with worms and viruses then block it. If not then let it through, as long as you have a rule that lets LW (and any computer) to connect to and from the internet.
As a rule, I always run my virus scanner after a marathon session on LW Pro, I have my MS Anti-Spyware set to run at 2.00am everyday and I run Ad-Aware SE every morning. In addition, whenever I use LW Pro I also use PeerGuardian 2; along with Prevx V2.0 and my other protection apps, which I religiously keep up to date, my PC is pretty safe.
