Whether you're an avid IRC user, visit certain types of forums or are vulnerable to attacks through services like Bit Torrent, you'll likely need a way to block certain countries or organizations from "talking" with your computer.
PeerBlock, which derives from Peer Guardian, is an effective tool at blocking hackers or copyright societies from accessing your PC or communicating with you through peer-to-peer networks. Essentially, it blocks either specific IP addresses or blocks of IP addresses.
Many of the known attackers are listed on filesharing forums. You may collect blocks of IP addresses such as governments and simply add them to PeerBlock.
Unfortunately, lists of IP addresses can become outdated fast. That has a negative effect on how well PeerBlock performs. Fortunately, you can also find updated blocks of IP addresses online which can block known hackers and snoopers.
PeerBlock is licensed as Freeware for Windows (32-bit and 64-bit) operating system / platform from firewalls without restrictions. PeerBlock 1.2 is available to all software users as a free download (Freeware).
Compatibility with this peer blocker software may vary, but will generally run fine under Microsoft Windows 10, 8, 8.1, 7, Vista and XP on either a 32-bit or 64-bit setup. A separate x64 version may be available from PeerBlock.
We have tested PeerBlock 1.2 against malware with several different programs. We certify that this program is clean of viruses, malware and trojans. [Read more]
