Be Ahead of the Internet Arms Race with PeerBlock

Download the latest version of PeerBlock

Firewall, Antivirus, & Antispyware software are essential security protection, but what about taking things further and blocking all activity from many known sources of threats? Meet PeerBlock, a program that maintains updated lists of verified bad, potentially suspect, and good IP addresses based on your choosing.  It's a bit more advanced than your average firewall and can safely be combined with (or reinforce) existing firewall software or hardware.

Strangely enough, most operating systems already have built-in IP blocking functionality with a Hosts file but these still remain empty & ignored by official security updates in OSs such as Windows. PeerBlock takes care of this issue with an alternative to the Hosts file that's constantly updated based on a massive community that stays up to date with the latest sources of threats on the internet. Whether you do a lot of file sharing or work with a lot of sensitive information, PeerBlock can protect you further in what is constantly an internet arms race between security and attackers.

The initial setup comes with the essential lists to choose from including known sources of intrusive surveillance (Anti-P2P), spyware, advertising, and education institutions for those paranoid of their theoretically above-average traffic monitoring. For advanced users, there are many additional lists to use at http://www.iblocklist.com/lists.php, however the initial lists should be fine for casual users.  If your interested in more lists, I've tested many & highly recommend adding: Primary Threats, Level 2, Level 3, Hijacked, DShield.  I don't recommend blocking education institutions unless you have no affiliations with them & no need to access their info whatsoever. Also be sure to Allow HTTP connections (website connections) or else you'll find a lot of pages with ads won't load as fast or at all as this feature is still a work-in-progress. You can turn this feature on and off as you please when you not browsing though.  The developers are still working on smoother web browsing with HTTP blocking.  In the rare case that a genuine connection gets blocked and you can temporarily disable PeerBlock or permanently allow that specific IP.
