Review PeerGuardian

PeerGuardian 2 is an IP filtering software designed to block the IP addresses of specific organizations and companies that may wish to harm the user's privacy while using the Internet and peer-to-peer networks. Unlike its predecessor, it does not require the installation of any drivers and blocks IP addresses much faster than before. On Windows 2000 and above, it blocks at the kernel level, acting against all protocols used within the Windows system. On Windows 98 or Me, it blocks only TCP (due to technical reasons, kernel-level blocking on 98/ME is not feasible) with the same high performance as the Windows 2000 version.

PeerGuardian 2 blocks IP addresses based on a list of IP addresses collected by many methods. By default, it collects IP addresses from the website. is a website that allows users to interact with and block IP addresses of specific organizations and companies. It was founded in early 2005 by and intended to be a platform-agnostic database using open-published formats.

The software is fully automatic. There is no need to install a driver; just run the program without visiting the control panel. The new startup wizard makes everything more straightforward than ever. More detailed settings can be configured from the interface, including logging and the ability to prevent websites from being blocked. It is possible to allow an individual IP address for some time or permanently, solving the problem of incorrect IP addresses. In addition, new management and reporting database systems allow users to play an active role in preventing friendly IPs from being blocked.

PeerGuardian 2 has been significantly improved compared to its predecessor and is very easy to use, thanks to its startup wizard. In addition, it features a revamped user interface and a history viewer that allows the user to search for lists by name, enable/disable lists without having to delete them, and use the list cache to reduce load times. It also includes an update tool that multitasks and can be canceled.

However, this version has some disadvantages. On Windows 98 or Me operating systems, it only blocks TCP, which means that other protocols will not be protected. In addition, some users have reported problems with error detection and slow IP blocking speed. Also, although PeerGuardian 2 offers the option to allow connections over HTTP, this can be unsafe if you are not sure that none of your P2P or insecure applications use those ports. Instead, it is better to allow specific IPs manually and do a proper investigation on any unknown IPs before allowing access.
