Norton Removing needed files

I downloaded the CryEngine Free SDK (http://www.cryengine.com/) and when i go to extract it, Norton removes nearly every file i need to run this program. I have absolutely no doubt that this is a safe program. yet it is constantly removing files. its REALLY irritating me. The risk is WS.Reputation.1

 

How do i stop Norton from removing the files automatically?
