    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.

    SmartScreen and Antimalware Service running Very High Power Usage

    I just set up a new Workstation use the HP Win10 software to do initial install (local account) They signed in to Insider and upgrade to 2036.1005. While I do NOT observe and notice and slow down (Workstatoin has Optane drive, lots of Memory) the task manager is constanly have the Windows Defender SmartScreen and Antimalware Service at the top of the list with VERY HIGH Power usage.

    I did a little online searching for solutions and most do not align with the Defender version on here. The only thing that fixes it is to complete turn off RealTime protection.

    Open to trying whatever you feel might help.

    Again....if I do NOT look at the task manager, I woudl never know I have something going on.

    PC has been setup and running now for three days.

    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.
