SimpleWall: Making Windows Firewall Truly Usable

One sentence solution: Some software always sneaks online to upload data in the background? SimpleWall lets you clearly see which programs are connecting to the internet and block them with one click.

Is the Windows built-in firewall secure? Yes. But can you tell me how to block a specific program from accessing the internet in Windows Firewall?

The process is too complex. SimpleWall makes it simple.
