I'm using Windows XP Home, Limewire v. 4.2.3 and have Avast v. 4 running as an antivirus aid. The Avast icon sitting in the system tray displays the following when activated by cursor contact:- 6 providors, 5 running. One of these providors is listed as 'P2P Shield'. Can someone please explain what these providors are and whether the P2P Shield can have an adverse affect on the operation of Limewire?
