"Whitelist" a file?

Hello!

 

I have a ElfBot NG on my computer, and Norton thinks that Elfbot's program file, loader.exe is infected with a trojan. Or is a trojan.

 

The program helps you to play Tibia, a game. I think, that Norton thinks that loader.exe is a virus because it modifyes tibia.exe. Could that be true?

 

And if so, how can I "whitelist" loader.exe so Norton stops detecting it as a trojan?

 

I have NIS 2009
