I am not sure if this is the correct forum for an obfuscation question, so sorry if it isn't.

I found a free obfuscator on line. The link is below. I tested it on a copy of my exe, and the .exe still worked after the process was done. How can I know if this program actually obfuscted the exe, and how well it did it. I am using Visual Basic 6. I am not looking for some top notch obfuscator, just some added protection.

Thank you for your information.
