Stop risky computers connecting with yours


  • Avoid problematic IP addresses.
  • Large amount of options.
  • Constant updates.


  • Some characteristics are a little complicated to understand.

As you might know, your computer stops being an ‘island’ as soon as you connect to the internet. Via the web, the potential of your PC increases no end, but so do the risks. And we’re not just talking about malware or the feared deep web, but also legitimate connections that don’t help in protecting your computer.

PeerBlock is a small program that protects your computer from IP addresses that put your computer at risk. In short, the program helps you choose which computers to connect with, which to avoid, and which to connect with only in certain circumstances. Even though it looks a little complicated, PeerBlock is more straightforward than you might think.

Less ads, less malware, less censorship

As soon as you start PeerBlock, for the first time, you’ll come across an assistant that will help you configure the program to suit your needs. What can you do with PeerBlock? Well, you can block the IP addresses of those sites that monitor your browsing while you use P2P programs (Ares, BitTorrent, and uTorrent, for example), and it’s possible to deny access to servers that emit commercials. You can even impede malicious programs.

The program achieves this in a pretty simple way—PeerBlock disables ports that aren’t used by your computer while downloading a list of IPs that have been flagged as risky. The lists are updated regularly so that your computer isn’t left at risk. If you have any doubts, don’t worry—PeerBlock has an explanation for every feature and also links to a load of online information to explain them in even more detail.

The average user knows very little about their computer, and even less what happens when their computer connects to the internet. Fortunately, programs such as PeerBlock make it simple, leaving you with an extra option when it comes to protecting your PC.
