Microsoft Defender Antivirus regularly scans your device to help keep it safe. We try to do this while you’re not using your device so it doesn’t interfere with your work. You can also schedule Microsoft Defender Antivirus to scan at a time and frequency that you choose.

  1. In the search box on your taskbar, enter Task Scheduler and open the app.

  2. In the left pane, expand Task Scheduler Library > Microsoft > Windows, and then scroll down and select the Windows Defender folder.

  3. In the top center pane, double-click Windows Defender Scheduled Scan.alternate text

  4. In the Windows Defender Scheduled Scan Properties (Local Computer) window, select the Triggers tab, go to the bottom of the window, and then select New.

  5. Specify how often you want scans to run and when you’d like them to start.
