IP address blocker PeerBlock, the successor of PeerGuardian, is an IP address blocker that can protect you from thousands of potentially harmful sites and computers. It uses multiple, categorized lists and you can choose which type of site(s) you want to block, including computers monitoring your p2p activities, spyware/malware sites, advertising servers and more. The lists are maintained and updated by a community and you can automatically have the program download the latest IP address lists. You can also create your own block lists based on your personal preference. PeerBlock keeps track of all blocked sites, and you can easily overwrite blocking rules or add new site directly from the log viewer. Copyright

Very useful addition to firewall software 5 stars by ianmacm Jan 17, 2014 (Read all my 174 reviews)
PeerBlock is not a substitute for firewall software, but is an excellent add-on for it. While the program is running, it provides an ongoing list of the traffic and IP addresses that it has blocked, and the reason why it was blocked. This is interesting in itself, and shows that there is a lot of junk traffic floating around on the Internet at any given time. PeerBlock uses lists of banned IP addresses maintained at, and in September 2013, the system there was changed so that free users can update the lists only once in seven days, and anything more than that requires a paid subscription. This means that PeerBlock is now a semi-free program, but for most users updating the lists once every seven days should be enough. PeerBlock is recommended, and is a must have for any program which uses P2P connections. show Review details
Will block the unwanted 5 stars by gimpguy Aug 08, 2011 (Read all my 1159 reviews)
This not only blocks unwanted sites but shows you and allows you to choose categories of what you want blocked, will also allow custom categories, although I haven't tackled that yet. You can customize the colors for blocked HTTP, text, etc... While still not 100 protection as with anything you use, this is a wonderful addition to help in that area. Glad it's free as well, you can't go wrong. show Review details
