well if you really want to know why your virus software rejects Firestorm, it's because it uses a tracking program to keep tabs on your system so when the Norton or defender handsakes your copy of Firestorm it picks it up and stops it, but no fear, it a passive program and is not meant to harm your computer, but some virus programs can't relate to the difference between passive and attacking programs.

Try using AVG it's way better than Norton
