    Windows Defender Smartscreen

    Windows Defender SmartScreen is constantly using 13-16% of my CPU resources. Is this normal? Seems to be bogging my computer down. Task manager shows Very High power usage and Very High power usage trend. This doesn't seem appropriate for a function
    that operates in the background and only on demand.

    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?

    Windows Defender SmartScreen cpu usage

    It says I have version 1809 (OS Build 17763.437). Should the SmartScreen program be 50% of my cpu capacity? Seems high for a background program that is running constantly.
