PeerBlock 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.
