If you want to remove Norton, I suppose the way to do it is
(Step 1) to remove it through Add/Remove Programs and then
(Step 2) run the Norton removal tool. Of course Windows 8 makes everything harder.
Since I've managed to avoid being stuck with the egregious horror that is Windows 8 thus far, I have to look up a good site for how to wrestle with it on the Internet.
This site seems to tell how to access Add/Remove Programshttp://www.dummies.com/how-to/content/add-or-remove-programs-in-windows-8.html
Here's another site that shows a different way to access Add/Remove Programshttp://blog.ilab8.com/2012/03/03/windows-8-not-that-easy-to-uninstall-programs/
So you get to Add/Remove Programs in a bizarre and putrid way, but it's still there in some form. I assume that once you find it, you can use it in the usual way to uninstall something, though I can't be 100% sure.
Step 2 - For the Norton Removal Tool, you can find it at our old friend Bleeping Computerhttp://www.bleepingcomputer.com/download/norton-removal-tool/
The Norton Removal Tool will make sure it's gone -- in case it didn't uninstall completely -- which it very well may not have. Be sure to run it as an Administrator.
Once you're done removing it, find a friendlier antivirus.
If you want to search for Norton and rassle with it a bit before deleting it, here's a site that tells you how to open "File Explorer" http://windows.microsoft.com/en-US/windows-8/files-folders-windows-explorer
Norton is probably in either C:\Program Files or C:\Program Files(x86)
