PeerBlock is excellent free security program that scans the connection you make with various websites while browsing online, and determines which one of them contains malicious software or aggressive advertisements. With very simple user interface, novice users can control the connections of their computer, effectively severing connection with the servers that are sending unwanted content, advertisement, p2p connections, hacker connections and more. By shutting connection to those servers your computer remains safe, and by using predefined lists you can deny access to wide variety of domains, governments, corporations or even domains from entire countries.
First version of PeerBlock appeared on the internet on 27 September 2009, created with the efforts of the three developers under the leadership of Mark Bulas. They took the code of older versions of PeerGuardian and infused it with better OS compatibility and more tools. As of early 2014, PeerBlock is available for use only in English language, and is still collecting money from donations for creation of their private online virtual servers that will serve as a central update service. For now, online updates of blocked content are performed with the help of the 3rd party servers.
Whether you want to protect yourself from outside threats or you want to hide your activities from other, PeerBlock is a perfect solution for you. It is very important to notice that the official supplier of the blocking lists that PeerBlock uses I-Blocklist has restricted access to free users of this app, offering them only ability to refresh their lists no more than once per week. Additional refreshes are possible with usage charges. This business arrangement was created in cooperation with the developers of PeerBlock, who are earning a peace of that subscription money.
Note: PeerBlock is a continuation of PeerGuardian. PeerBlock is much more stable, doesn't require nearly so many hacks/workarounds to get working on Vista/Windows 7.
