PeerGuardian is compatible with all TCP/IP based file sharing applications, such as Kazaa, iMesh, LimeWire, eMule, Grokster, DC++, Shareaza, 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 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.
PeerGuardian is a powerful yet petite firewall application especially designed for P2P users and anyone else who wants to protect his or her computer from unauthorized searches instigated by private agencies and corporations.
