Windows Defender Antivirus helps protect your PC against malware (malicious software) like viruses, spyware, and other potentially unwanted software. Malware can infect your PC without your knowledge: it might install itself from an email message, when you connect to the Internet, or when you install certain apps using a USB flash drive, CD, DVD, or other removable media. Some malware can also be programmed to run at unexpected times, not only when it's installed.

Windows Defender Antivirus is included with Windows and helps keep malware from infecting your PC in two ways:
  • Providing real-time protection. Windows Defender notifies you when malware tries to install itself or run on your PC. It also notifies you when apps try to change important settings.
  • Providing anytime scanning options. Windows Defender automatically scans your PC for installed malware on a regular basis, but you can also manually start a scan whenever you want. Windows Defender automatically removes (or temporarily quarantines) anything that's detected during a scan.

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

This tutorial will show you how to schedule a scan in Windows Defender Antivirus for when you want in Windows 10.

Here's How:

1. Press the Win+R keys to open Run, type taskschd.msc into Run, and click/tap on OK to open Task Scheduler.

2. Expand open the Task Scheduler Library > Microsoft > Windows folders in the left pane of Task Scheduler, and click/tap on the Windows Defender folder. (see screenshot below step 3)

3. Double click/tap on the Windows Defender Scheduled Scan task in the center pane of Task Scheduler. (see screenshot below)
