Poisoned is a Mac client for the popular Kazaa peer-to-peer file sharing network. Poisoned is a free download for Mac OSX 10.2
Poisoned uses the giFT daemon which is capable of facilitating the communication between the end user and specific filesharing protocols (namely gnutella and FastTrack). This means that when you use Poisoned, you are not only searching the Kazaa network, you are searching the Gnutella network as well (Limewire uses the gnutella network).
Best of all – Poisoned is a native Mac OSX application, so it performs very well (unlike Limewire which is a slow Java app). Poisoned does not use adware or spyware – unlike Kazaa.
