Freeware Tools: PeerBlock 1.2

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.

As the name suggests PeerBlock, is an app that prevents unsecured locations from accessing your computer, in order to protect your sensitive data. It can be easily figured out.

Upon initialization, you can use a wizard to specify the types of ranges you want to block. These can be either peer-to-peer organizations (P2P), ads, spyware or educational institutions.

Alternatively, you can import or create custom lists as well as always allow the computer to connect via port 80 and 443, even if they are blacklisted. In the last step, you can enable the app to check for updates (PeerBlock, lists, or both), on a regular basis (e.g. daily, weekly).

The main application window shows the time, range, source, destination and protocol for each connection. Enabling and disabling PeerBlock's status can be done with the simple click of a button.

Moreover, you can view a history list or clear the log file, customize settings when it comes to the log window, history and notifications, make the app automatically run at system startup and start minimized to the system tray area, among others.
