AKLT (AntiKeyLoggerTester) is a portable single executable program file that will allow you to test your computers protection from keylogging malware. There are 12 tests you can perform including two screenshot tests.
When you click on the first 10 tests, if you can type on your keyboard and the symbols appear in the Captured keys screen display, then you are not protected from that test.
If you are protected, a green checkmark will appear and "Nothing Intercepted Until Now" will be displayed, and none of the keys you typed will display in the program, which means the test was blocked by your anti-keylogger program. Your anti-keylogger program should also give you an alert to allow or deny the attempt.
The two screenshot tests should not be able to capture an image of your screen. The attempted screenshot capture by AKLT will put the jpg image it tried to take on your desktop.
