We don't know why programs like Norton pick it up as a virus but it's most likely due to the fact that it hasn't been scanned by Norton themselves, and because it has the ability to connect to the internet. If you get some sort of warning from your anti-virus, ignore it. (i would advise putting the downloaded application in an easy to access location i.e desktop)
