Norton 360 and Audacity audio capture software

I am trying to run the latest version of Audacity (2.1.3) either today or yesterday's build.  I can download the zip file and extract it.  I scanned with Norton 360, both the zip file and unzipped directory, and Norton reported no problems.  I tried running the program and can the screen that said that there were not many users and the program is very new(duh).  I said run anyway and Norton complained about some of the dll files and deleted them which caused the program to fail.  How can I get this done?  Can I tell Norton that these files are good and leave them alone?
