In order to change SLI settings with my nvidia driver, it tells me I have to shut down "nbsu.exe" to continue. This is a Norton process that cannot be stopped, and NAV provides no way to temporarily shut it off.
This used to work fine, so I assume it's a bug with either nvidia or Norton. Regardless, I need my video card more than I need Norton, so I've uninstalled it.
P.S. the link to provide feedback on "why you're leaving Norton" doesn't do anything when you click on it. That about says it all.
