How to do offline virus scan with Microsoft Defender on Windows 10

If your PC gets infected with nasty malware, you can use the Microsoft Defender Offline scan to remove it — here's how to use the tool on Windows 10.

Microsoft Defender Offline

Sometimes malware and other malicious software can be very difficult to remove when you are signed in to your device. However, if you have Windows 10, you can use the Microsoft Defender Offline feature to scan and remove all types of malware, including viruses, rootkit, ransomware, and other malicious software no matter how tough they are.

The offline virus scan feature has been part of the Microsoft Defender Antivirus for a long time, and it allows the antivirus to run without loading Windows 10 during startup. This is particularly useful because when your device is infected with a particular persistent malware, it’s extremely complicated to remove it while Windows is fully loaded.

In this guide, you will learn the steps to use the offline virus scan feature to remove rootkit, ransomware, and other nasty viruses on Windows 10.
