this is a small program that creates a file in the root of drive C: \ and Run key in the registry.
Avast should trigger the feature autosandbox this file, so you can check if the feature is working as expected (the last version 6.0.1091, it should work on all operating systems supported). If the file is not autosandbox, there may be some here in problem.tested machine both in ask how the automatic option, the file is no longer running in the autosandbox. ???
