Thanks to the bitcointalk and reddit communit(ies) for making this known.  I'll make sure and make a post about it to the Unsystem list, where the developer of sx (which is not malware, but was used by the Stealthbit author(s) apparently) will I'm sure address it and provide some advice.  Fortunately, I didn't touch the Bitvanity or Stealthbit stuff - and it's obvious that the person(s) who designed Bitvanity/Stealthbit are thieves, now I guess the question is, what does the community of developers do about it.  Time to pop that question.
