Stopzilla includes spyware .. which is most likely the culprit. Option is to put LW or other p2p sharing programs on its safe list (if it includes such an option which it should), else choose another spyware program that 'is' p2p safe. Many spyware programmers do not like p2p software thus program them as detecting p2p sharing programs as having spyware even when they don't really have.
