Open Your Norton Anti virus and go to options

On the left hand side of of the box click Internet Worm Protection.

Click Program control button and remove any references to LW, close then restart LW
Click permit the first time it comes up and it should be working ok.

I only know this as the remedy was in another thread on this site http://www.gnutellaforums.com/showth...orm+protection

Good Luck
