That makes it useful when malware keeps returning or may be hiding while Windows is running. Save your work first; the scan restarts the computer. Open Windows Security > Virus & threat protection > Scan options, choose Microsoft Defender Antivirus (offline scan), then start the scan. Microsoft explains the scan and where to check its results.
What an offline virus scan does
Microsoft Defender Offline restarts the PC and runs from the Windows Recovery Environment rather than from your usual Windows session. Scanning outside the normal session can help when malware is difficult to detect or remove while Windows is running. “Offline” describes where the scan runs; it does not mean you need a separate paid antivirus product or a USB drive.

Microsoft describes Defender Offline as a quick scan, but it is not a guaranteed fix for every infection. If malware returns or Windows cannot recover normally, you may need to move on to broader recovery steps.
Run Microsoft Defender Offline
- Save open work. Starting the scan restarts the PC, so save documents and close anything you are working on.
- Open the scan settings. In Windows Security, go to Virus & threat protection > Scan options.
- Choose the offline scan. Select Microsoft Defender Antivirus (offline scan), then start the scan. Labels and available options can vary with Windows version or device configuration.
- Let the PC restart and scan. Defender Offline loads in the Windows Recovery Environment, runs the scan, then restarts the computer when it finishes.
- Review the result. Open Windows Security > Protection history to see detections and actions taken. See Microsoft’s guide to Virus & threat protection for scan and history details.
If the offline scan option is missing
First confirm you are looking in Windows Security > Virus & threat protection > Scan options. Microsoft notes that labels or options can differ by version or configuration. If the offline scan still is not listed, use the scan options available on your PC and consult Microsoft’s malware detection and removal troubleshooting guidance for the situation.

Choose the next step if malware persists
| Situation | Next step | Disruption and risk |
|---|---|---|
| Windows starts and you want a routine check | Run a scan from Windows Security. | Runs in the normal Windows session; it does not provide the outside-Windows scanning environment of Defender Offline. |
| Malware returns or may be hiding while Windows runs | Run Microsoft Defender Offline. | Requires a restart and saved work. It can help with persistent malware, but does not guarantee removal. |
| Problems continue, or normal recovery does not work | Consider reinstalling Windows from installation media and selecting a clean installation. Review Microsoft’s Windows recovery options before proceeding. | A clean installation removes data from the selected drive. Back up what you can and understand your recovery needs before starting. |
When Windows will not start or recover
If the PC will not respond to its recovery options, Microsoft says you can create Windows installation media using another working PC and a USB drive. That is a fallback for Windows recovery or reinstallation—not a requirement for running Defender Offline. Before a clean installation, consider which files and settings you need to preserve and how you will restore them; the selected drive’s data can be erased. Microsoft’s recovery guidance covers the available routes.
