Windows Defender SmartScreen cpu usage

My computer has been running slow and I noticed that Windows Defender SmartScreen is using 45-55% of my cpu capacity. I have Windows 10 and Norton anti-virus on the computer. I looked in the forums and it sounds like this should be off when running another
anti-virus program. Should happen automatically according to one thread, but it is definitely running. Went into Security & Maintenance where it shows to turn it off manually, but the “Change Windows SmartScreen settings” option is not on the left side to
click. Using “End task” in Task Manager but it keeps coming back. Do I need this when I have Norton installed? If not, where can I turn it off?
