Though it's not as attractive as LimeWire, peer-to-peer (P2P) file-sharing application Ares 1.88 offers unrestricted searches, and it tested completely clean in our informal spyware tests. Still, the pop-up-ridden behavior of the main Web site and the discovery of two mysterious files after uninstalling the application left us wary. Ares is open source and available in a number of variations, such as Ares Gold, Ares P2P 2.1, and Ares Galaxy. Ares is the only P2P client we're aware of that includes online chat. Because it uses its own Gnutella network, Ares doesn't return as many search hits as some other clients we tested, but it produces fewer fake files. You can't beat the price, so give it a shot, but make sure your spyware protection is up-to-date.
