Limewire does contain spyware. In fact, it contains a few traces of it, including PRO. It contains KaZaA, Grokster, and a few others. Grokster installs: Active Delivery, CasinoOnNet, ClipGenie, CommonName, Cydoor, DelFin Media Viewer, DownloadWare, eUniverse, FavoriteMan, FlashTrack, Gator, IGetNet, IGetNet/ClearSearch, IncrediFind, IPInsight, Look2Me, Lycos.SideSearch, NetworkEssentials, NetworkEssentials/SCBar, PeopleOnPage, RVP, SAHAgent, Search-EXE, SearchEnhancement, TOPicks, VX2/e, VX2/f, and Webhancer. It also degrades your network performance vastly. You can't fully remove KazaA and Grokster unless you remove limewire and scan your computer and remove these programs. These are located in the magnet folder and the registry.
