Easily Blocking Application in Windows Firewall with Firewall App Blocker


Blocking an application in Windows through Windows Firewall takes quite a few steps. You will need to go to Control Panel, click on System and Security, and select Allow a program through Windows Firewall in the Windows Firewall section. And if the application isn’t listed there, you will need to add them by going to Allow another program…

With Firewall App Blocker, all you need to do could be simply like a drag & drop. Download the tool in Zip format which contains two copies of executable file for either 32 or 64-bit of Windows. It’s portable so just extract the file and simply launch it. Since it requires the changes to the system, you need to pass the UAC before using it.

Once the application open, you can simply drop the executable applications, not the shortcuts, to the list. And they will be immediately blocked in Windows Firewall. You can also use Add button to manually select the application if drag-n-drop isn’t so convenient.

For example, I drag and dropped FileZilla into it, clicked on Apply button.

And the change is done almost right away in the Windows Firewall.

Now, when I open FileZilla and try to connect to my FTP site, I wouldn’t able to connect it.

To unblock, easily remove the items from the App Block list, or choose Unblock inside the app.

The latest version of Firewall App Blocker also added a useful feature called “Add to exe context menu”. When enabled from Options menu, you will be able to block/unblock a specific app right from Windows Explorer right-click context menu, making things more easier.


Firewall App Blocker runs properly if the Windows Firewall is enabled and runs properly on Vista, Windows 7 and Windows 8 machine. Both 32bit and 64bit editions are supported.

The tool doesn’t change Windows Firewall default settings, nor add anything new that Windows Firewall doesn’t have, but does ease the process of blocking/unblocking a certain applications.



  1. Nice article. Unfortunately I fear that security is only done if manually done. It doesn’t protect from malicious software which installs itself by bad appz or bad web.

    To get real aware -security wise- someone should get an antivirus/firewall combination. There are many programs out there which will tell you that a application is trying to access internet. I can only recommend Avira because I use it myself for over 10 years already and never had a bad experience -malware/virus wise.

    Hope it helps.
