    Windows Defender Smartscreen is using 40% of my CPU constantly need help


    Hello,

    I am having an issue with Windows Defender Smartscreen using up a lot of CPU. and I just ran a full scan on my computer that finished a couple of hours ago so it shouldn't be trying to run another full scan.

    I am really unsure of what to do.

    I am running windows 10 with a SSD btw.

    Thanks for the help!

    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.

    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.

    Microsoft Defender Smartscreen

    Hi COLINGILBERT1,

    Sorry to hear you're experiencing this issue. I'm an Independent Advisor and consumer of Microsoft products just like you. Let me help you with your concern.

    Microsoft Defender SmartScreen checks downloaded files against a list of reported malicious software sites and known unsafe programs and against list of files that are well known and downloaded by many Windows users. If the file you downloaded is on the malicious
    list or is not commonly downloaded it will show a warning, advising caution. If you believe that the file is not malicious and you trust the source then you can ignore the warning by clicking "Run anyway".

    Refer to the below link for the benefits of Microsoft Defender SmartScreen.
