logoPeerBlock Plus Portable has been released. PeerBlock is an IP firewall with support for blocklists and allow lists. PeerBlock Plus adds a freely sourced blocklist that is automatically updated daily. It's packaged in Format so it can easily integrate with the Platform. And it's open source and completely free.

Update automatically or install from the portable app store in the Platform.


ScreenshotPeerBlock is an IP-based block and allowlist that lets you block communication with advertising, spyware, p2p monitoring, and other servers online. The included blocklist provider, iBlockList, allows users to update their lists once per week for free. Daily updates are available with a paid subscription. PeerBlock Plus Portable adds a freely sourced combined blocklist that is automatically updated daily when starting the app using a custom updater we created. The list provider accepts donations to fund their efforts. Both the 32-bit and 64-bit versions or the modern and legacy versions are included for maximum performance and compatibility.

I've updated PeerBlock with a custom updater to do daily updates of a freely available combined blocklist. This should make PeerBlock more useful to a wider arrary of folks.

Sometimes, the impossible can become possible, if you're awesome!


Better than manually deleting the lists.
PS. It was not updating (weekly) since a long time, not updating at all for free users.

Hi John,
What is this "custom updater" exactly? A malicious IP list? Where do you get it from?
Thanks in advance for your help!

Best regards,

It's detailed and linked above as well as on the app's homepage. You'll find a sources.txt that details all the sources the developer pulls from linked as well as a donation link to support them.

There was a great (huge) and free list curated by John at Bitsurge but his site has been down and he warned everyone that eventually he won't be providing it. Anyone has a link or suggestion on an alternative?
