Packer(or Crypter or Whatever) is changed?
After passing the UPX layer , we endup in some piece of code , which is obviously not output of any normal compiler. That binary has additional protection layer we can only assume if generated by builder but most likelly its just crypted with some crypter. Also notice the BitDefenter VersionInfo which is used to stop some Bitdefender signature probably. I seen this version info at more malware samples.
