Wowmapper Installer

I wish to use an Xbox controller on my PC to play World of Warcraft (WOW). In order to do this, I must download and install an "addon" program. Consoleport is just such a program: ConsolePort

The download instructions require the user to install Wowmapper. This  executable program Wowmapper_Installer.exe configures the controller for use in WOW. However, Norton quarantines and deletes the executable program. I checked on the WOW forum and most believe that the program is safe, so many have used it. However, no one is certain, and Norton's actions concern me about using this program. What should I do? Download it and hope for the best? I have contacted the developer, but this far he has not responded to my email. How do I determine if it's safe to use?
