The files you downld do not come from a site. They come from other users like yourself. But yes there are organisations out there such as Overpeers who spam the network with fake files. Well the problem should be fixed with LW 4.12.3 & has fixed the problem for almost everybody except a couple who have posted in this thread. I wonder if they are 'really' using LW 4.12.3
Perhaps deleting the LW prefs folder might help; Try deleting your LW Preferences folder whilst LW is closed; instructions here: Point #2 & 3 in Fixes for Limewire (sample image included at bottom of page.)

If you don't update then you will always have the napster problem.
