PeerGuardian is a powerful yet small firewall program that was especially designed for P2P users who want to protect their computers from unauthorized searches instigated by private agencies and corporations.
PeerGuardian works by blocking and logging all TCP/IP connections to and from known IP ranges used by known P2P foes, such as the RIAA, MPAA, MediaForce, MediaDefender, BaySTP, Ranger, OverPeer, NetPD, and more. To make sure that the block-list used to block malicious connections is up to date; PeerGuardian uses an on-line block-list Database that is continuously updated on a daily basis — so your privacy will remain safe while swapping files.
PeerGuardian is compatible with all TCP/IP based file sharing applications, such as Kazaa, iMesh, LimeWire, eMule, Grokster, DC++, Shareaza, and more. In short, PeerGuardian is the must have tool for any file swapper.
PeerGuardian is not advertising supported, nor does it require registration, and no information is collected from or about product users.
