Interference with my code!!

I am a biophysicist who writes extensive code analyzing my data. I wrote a small program to stay resident in memory and, when a hotkey is pressed, just copy a backup data file to a data file that I have to constantly re-analyze by hand. This new version of Norton keeps removing the memory resident program as a high risk virus. Furthermore, when I tell the program to reinstate it and take no action in the future, whenever the computer is rebooted it once again attacks my program. This must stop!!! I need to be able to tell Norton to leave my programs alone PERMANENTLY. Any advice???
