My understanding is that Shareaza, KLR(Kazaa Lite), etc. have a limited built-in block list, which LW & LW Pro does not posses.
I would suggest that you download and install PeerGuardian 2 (beta 5b) available from here:
http://www.methlabs.org
It has the most comprehensive group of block lists of any utility on the internet at the moment and the lists it uses are constantly updated.
I now never use LW Pro without activating PeerGuardian 2 first, and I can guarantee that you will be surprised when you read your first PG2 log by the number and kinds of organisations that sneak into your PC when you are using LW.
