Antivirus inhibiting development of DLL

I have Norton Internet Security 22.9.0.68. I am doing software development of an interface DLL.  NIS thinks it is a threat and removes it each time I build it.  Restoring it is useless since each time I build NIS treats it as a new file and I am rebuilding mutiple times each hour.  The only option I could come up  with is turn anti-virus off and that is not very desirable. Is there another option that I can use so it ignores this DLL and any future builds of it?
