Game Launcher does not have any viruses. It's quite common for anti-virus software to give false alerts on mods and stuff.

Game launcher has a number of threads over on Terraria Online and is widely used by lots of people, I don't see any reason to distrust it (I use it myself). You just have to figure out how to get Norton to ignore it, because Norton is a bit retarded sometimes.
