What is Norton 360 Permier doing?

Why is my Norton 360 premier identifying competitive programs as a detected threat? e.g., RegCurePro and WS.SecurityRisk.3? I think I have my security structure under control and then these threats start showing up. How do I know these are or are not threats and how do I trust what Norton is telling me? I understand RegCurePro is a Windows security tool and WE.SecurityRisk.3 is a cloud based security tool, why are these risks that require some action? How do I resolve these from constantly showing up? The RegCurePro I've "Excluded" three times now and it still gets listed as a Threat Detected. Any suggestions or help you can provide?
