PeerBlock filters Internet connections from addresses of organizations and corporations that may harm user privacy while using the Internet and P2P networks. The program also contains a "Block HTTP" feature for use with web browsers that blocks advertisements, sites associated with spyware, and more. PeerBlock is a fork of the popular but inactive PeerGuardian, adding features and fixes as well as Windows Vista/7/8 and 64-bit versions.

Alternatively, Peerblock Portable is stealth and automatically selects the proper Peerblock variant for the current PC.

Runs on:WinXP / Vista / Win7 / Win8
Writes settings to: Application folder
Dependencies: Administrative rights
Stealth: ? No. Leaves registry entries: HKLM\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_IPFILTERDRIVER and HKLM\SYSTEM\CurrentControlSet\Services\IpFilterDriver\Enum
License: GPL and zlib/libpng
How to extract:
  1. Download the ZIP package for your operating system and extract to a folder of your choice. Note that there are four variants: standard WinXP 32-bit & 64-bit, and Vista+ 32-bit and 64-bit
  2. Launch peerblock.exe
  3. When prompted, select types of organizations you would like to block

What's new?
  • Port Allow List - The new "Port Settings" tab allows you to unblock ports (incoming and/or outgoing). This means that PeerBlock will not filter any connections from/to those ports. This can for example be used if you're running PeerBlock on a public FTP server, or if you want to ensure that outgoing SMTP mail communications are never blocked. Many thanks to night_stalker_z for his hard work on this feature!
  • First-run Update Message - When you first run PeerBlock after upgrading, you will see a notice explaining why lists are only updating once per week. Hopefully this will help to alleviate people's confusion about this.
  • Better Weekly List-Updating - We've made some improvements that should help ensure that free users continue to get their free weekly list-updates.
  • I-Blocklist Subscription Settings - To make it easier for you to configure PeerBlock to use an I-Blocklist Subscription, new I-Blocklist Username/PIN fields have been added to the bottom of the "Settings 1" tab.
  • Separate Settings Tabs - Instead of having one Settings tab with those silly "Next" and "Prev" buttons on it, we've broken that out into two separate "Settings 1" and "Settings 2" tabs.
  • Improved List-Update Error Handling - We've worked with I-Blocklist, who hosts the vast majority of the lists people use, to create improved error messaging for the various problems that may occur when updating lists. If something occurs during update-checking, the error message displayed should be much more meaningful.
  • Improved List-update Error Window - Should you hit any errors while updating your lists - 429 or otherwise - we will now pop up a more informative error window, along with a button you can click to jump straight to our site to check for more information.
  • Updated Error Windows - If you encounter a catastrophic error, the message that appears will now tell you to go visit This will redirect you to a forum-post on which the most common error-messages are displayed, to help you figure out what has gone wrong, and what can be done to fix it.
  • (Re)Load Previously Downloaded Lists - Previously, there was a problem where if you disabled and then re-enabled a list in the List Manager, that list wouldn't be reloaded until it successfully downloaded an update. Now, if it can't update that list it will still load the last version you did successfully download.
  • Removal of Windows 2000 Support - Windows 2000 is quite old by now, we hope that nobody's still running it; if you are, you can continue using the previous PeerBlock version. This release does support all Windows variants from Windows XP through to Windows 8.1, including server variants. (But not Windows RT.)

I have downvoted the entry because the updates have gone payware and I have not been able to update the database in a while.

Awesome program. Can function as an adblock and also anti-P2P companies snooping around where they don't belong! Indispensable tool for any serious computer geek.

V1.1 r518

Magibon 2011-03-09 02:11

great software!

i am running x64, and this works perfectly!

of course, you're never 100% safe from nosy ISPs, so i use this in conjunction with IPFilter µpdater, also very light, portable, and stealth.

Reading the FAQs from their website:
"Bear Principle": when running away from an angry bear you don't need to be faster than that bear... you only need to be faster than the guy next to you.

@Wolfghost: I wasn't referring to you, Wolfghost. I was referring to the program description on top that says

»Note: This beta version contains more features but has been less thoroughly tested by the developers. As this program is by nature a security program, some users may wish to use the stable version.«

That would need to be changed.

@Meks: At the date I wrote this [2010-10-22 20:15]
It was new !! Thanks anyway for let us know about updates.

Meks 2010-11-24 20:06

Just so you know: V1.1 r518 is the next STABLE release; so, the note above about beta version is not accurate.
Website says:
»Here it is, PeerBlock 1.1, released November 22, 2010!
