Sounds to me like your Limewire got like it got corrupt. You may have to uninstall it and start fresh. and rename the folders that you dontwant shared so LW wont recognize them again. you picked up something from Gnutella. Unistall LW quickly, deleted all the leftover folders, move your downloads to another folder, rename it, reboot your computer, scan and defrag your system, then, start fresh.
