Unable to install Norton Security

I am running WIN 7 Pro with a virtual XP sp3.  I have been using Norton 360.  That is now a legacy product.  I need to install by 2/8 or 2/9 as the previous product will expire.  I tried to install Norton security.  The package says it will support WIN 7 and XP.  I tried the XP first.  It sort of installed.  I even, somehow got it registered.  But I cannot get to the internet with my browsers.  Also the CPU is at max usage as it is trying to find a fix to a problem.  It can't find a fix because it can't get to the internet.  I even uninstalled and reinstalled. 

The previous product worked just fine.  I am reluctant to try installing it on the WIN 7 Pro machine.

Any help would be appreciated.

 

Thanks
