Moreover (and this is where the viruskiller analogy ends), PeerBlock will make you harder to detect compared to others on the network the PeerBlock documentation cites the so-called “bear principle: “when running away from an angry bear you don’t need to be faster than that bear … you only need to be faster than the guy next to you”. In keeping with the virus killer analogy above, PeerBlock will not necessarily protect you from the latest unknown threat or bad IP, but it will greatly decrease your chances of being detected. It works much in the same way as a virus killer program in that it is constantly updating the lists of known “bad” IP addresses, even as more of these come into existence. It utilizes the collective wisdom of communities and sites that classify IP addresses (go here for more on where these lists come from). What PeerBlock does is it taps into publicly available lists that classify IP addresses in order to simply avoid “bad” IP addresses. Typically, agencies that are out to detect people’s downloading activity will actually take part in providing the file for download, then attempt to find out as much information about the computers that connect to them as possible. If you’ve ever read or heard about ordinary people being sued for downloading files from torrent or other p2p networks, and worried about your own downloading activities, this program is for you. PeerBlock is available in portable form and works with all versions of Windows (including XP, Vista, Seven). This can significantly decrease your chances of being detected when downloading from p2p or Torrent networks, or of contracting malware/spyware from known sources. It is designed to prevent your computer from making undesirable connections, such as to machines flagged for anti p2p activities, corporations, governments, etc. PeerBlock is an open source IP filtering application partially based on the PeerGuardian code.
