It’s a tiny program that creates a file in the root of disk C:\ and in the registry Run key.
Avast should trigger the autosandbox feature on this file, so you can test whether the feature is working as expected (in the latest version 6.0.1091, it should work on all supported OSes). If the file is not autosandboxed, there may be some problem.
Does not work for me.
COCKPIT ERROR: I see that with the Opera dialog I was just downloading it, not executing, so when I selected the right answer it worked. But when I selected “don’t execute”, I got a BSOD as a bonus. Will send the minidump to you.
