PeerBlock is a free software firewall

http://www.peerblock.com/

PeerBlock is a free software firewall application. PeerBlock is the successor to PeerGuardian (which is no longer actively maintained[1]).  It blocks incoming and outgoing connections to Internet IP addresses that are included on blocklists accessible over the Internet which may be selected by the user, but also any addresses manually specified by the user.[1] PeerBlock mainly works in tandem with the blocklist provider iblocklist.com.


PeerBlock lets you control who your computer "talks to" on the Internet.  By selecting appropriate lists of "known bad" computers, you can block communication with advertising or spyware oriented servers, computers monitoring your p2p activities, computers which have been "hacked", even entire countries!  They can't get in to your computer, and your computer won't try to send them anything either.


PeerBlock History

(TODO:  talk about how we forked from PeerGuardian, user donations, etc)

Years ago there was a program called "Peer Guardian", which was a pretty good IP Blocker.  The developers of Peer Guardian appear to have abandoned it back in 2007, after releasing a "Beta" that included initial support for Windows Vista.  This version was the only version that worked on Vista (and now Windows 7), and required all sorts of hacks and workarounds to get it to run more-or-less successfully.  There were also a lot of bugs in the source code for Peer Guardian, such that even after applying all the workarounds it still would fail with relative ease.
