Digmor,

HelloWorld2 is the test program that CryptoPrevent creates to test itself. When you hit the test button, it (temporarily, as best as I can tell) creates HelloWorld2.exe in a monitored area [for example, C:\Users\your name\AppData\Roaming\ ] and tries to run it from there. If blocked, the test is successful. After you run a successful test, you can see this result displayed by clicking the Event Log button, then Blocked Events. Click on the date/time in the left-hand column, to display the details of the Test Event in the right-hand column.
