In Windows, you can use Windows Firewall to block or unblock certain applications, but it doesn’t offer an easy-to-use interface for its advanced features. Firewall App Blocker makes the process very easy! Simply drag and drop the application you wish to block into the FAB window, or browse the hard disk to find it and block it through context menu. That’s it! If you want to allow it access again, you need only select it and press the Delete button. FAB doesn’t do anything that Windows can’t do itself, however it provides a much simpler means to select which programs will be blocked. Best of all, it makes it very easy to add multiple programs to the firewall simultaneously!
