Pondus,

Does that mean that the samples differ for they have unique identifiers?
That is why I uploaded the source url to Anubis for analyzing and will look at the results,
here are the scan results for you, the MD5 hash for the Anubis scan = 3f878f42af7fe3f2729f94e30baa5db2
Now avast detects as Win32:Spyware-gen [Spy] your sample
My sample isn’t detected.
