Oh, thanks a lot, guys. So much for my sense of security, thinking that not having source available would protect me from the criminals.
I wasn't aware that an .msi could be post-infected.
In any case, I think I'll still hold on to my source code. But I'll still be happy to provide assistance and lots of encouragement to anyone who'd like to try a port. I've done so in the past, and I make a pretty good cheerleader. 
Thanks for the info, guys. (This time it's sincere. The first 'thanks' was sarcastic hehehehe)
