Norton for Mac OS X with Windows via VM Fusion

I am running Mac OS X (10.6) but also need real Windows for other work, so I have VM Fusion with Windows 7 installed. My subscription is about to expire. I currently have Norton running on the Mac and I have a separate Windows version running on VM Fusion to protect the Windows system when it is running, since it does not talk to the Mac system. Does the Norton dual product cover those two systems? What I read on the Norton site leaves the impression that this product protects Windows Apps that are probably running in Boot Camp and I need the Full Windows protection. Will the dual product work or do I need to continue to buy a Windows version and a separate Mac version?
