Atelier Web Firewall Tester (AWFT) is a once commercial, now free tool which uses multiple techniques to try and bypass your security software and contact the outside world.

(This may raise security alerts in some situations, but it is not dangerous in any way. The program has been around for years, and is entirely safe -- all it's doing is trying to access and display information found on the developer's website.)

AWFT supports six tests, and displays a button for each on the main window.

Hovering your mouse cursor over a button displays a tooltip explaining what it's going to do. Test #1 "attempts to load a copy of the default browser and patch it in memory before it executes", for instance, while Test #3 "creates a thread on Windows Explorer".

Clicking any of these buttons runs the appropriate test. Some tests ask for further input - a process to hijack, maybe - and then display either a success or failure message.

A running score keeps you up-to-date with "Firewall Points" (tests your system has passed) and "AWFT Points" (tests your PC has failed).

A "Reset Points" button sets both scores to zero, giving you time to tweak your security settings and try again.
