If you have any supporting screenshots, please add them:

Did you have another security software installed before installing Norton? Even a trial version would need to be fully removed using the removal utility for that software before installing Norton.

I had Avast on my computer but I uninstalled it

How long have you had Norton installed? Have you manually run LiveUpdate a couple of times, restarting your computer after each run of LiveUpdate?

What version of Windows are you using?
What version of 360 are you using? v22.x.x.x or v24.x.x.x? There have been reports of v24 having performance issues.
