i deducted that, as someone said upper on the posts chain, "it could ve a virus", but if P2P networking isn't allowed, i think the virus attached it's code to Lw installer, send your Pc's Ip's to ahacker, and the last one injected a copy to all the computers, and as Lw is a so-trusted app. nothing suspicious happened -in the top of the thing-, that's waht i think, hope it helps to you...
