Just found that Nucoder encoded scripts seems decoded by automated tool here. Anyone can confirm or any solution to prevent this?

Unfortunately I've test it and it's working.

I really hope NuSphere to confirm some solution, or my money will be gone for nothing.

It appears to be fake. As of version 3, 3, 4, 0 (Jan 25, 2010) DeZender
just converts php file encoded with NuCoder 2.0 into another file which is
still binary. No sources are extracted. See the screenshots below:

Before:



After:



Furthermore, some of files on the site mentioned above are infected with viruses.
