    do i need to install defender updates? I am using avast antivirus

  • http://www.thewindowsclub.com Anand Khanse

    Defender will disable itself if you have Avast installed. No you do not need to update Defender. Should you wish to, you will have to disable Avast, activate Windows Defender and then update it. After that you can activate Avast again.
