I don't know if the software is malware or legit, haven't tested it myself.
However, people should really be concerned about running software from unknown sources.
I have seen some altcoin launched this way and people are running the software blindly so this works for the launch, but again, we should not encourage this methodology.
IMHO, you should place the idea and some code to review, this will generate debate and possibly improvements to the original code and at the same time will show the effort put in it.
I really like your idea and if it works it will surely have a place among the recent altcoins.
But I will not run your exes
People should read this post by Gavin Andersen and apply his methodology :
