Can't find version of Internet Security for Mac, version checker not helpful.

Norton 360 for Mac
1

I am having a difficult time renewing Norton Internet Security for Mac because I can't find its version. When I check versions, I find NAV 11 for Mac and Norton Confidential v1 for Mac. Aren't these bundled together to make Norton Internet Security for Mac? So where on my computer does it say if it's Version 3 or Version 4?
