This option is useful when you don’t want to spend the time running a full scan on all your files and folders. Concerned that you may have done something to introduce a suspicious file or virus to your device? Select Quick scan (called Scan now in previous versions of Windows 10) to immediately check your device for any recent threats. Run the scans you wantĮven though Windows Security is turned on and scans your device automatically, you can perform an additional scan whenever you want. Note: If you are using third-party antivirus software, you’ll be able to use its virus and threat protection options here.

See threats that have been quarantined before they can affect you and anything identified as a threat that you have allowed to run on your device. Start a new quick scan or go into scan options to run a more extensive or custom scan. See the last time a scan was run on your device, how long it took, and how many files were scanned. See any threats currently found on your device. You can also run different types of scans, see the results of your previous virus and threat scans, and get the latest protection offered by Microsoft Defender Antivirus.

Virus & threat protection in Windows Security helps you scan for threats on your device. In early versions of Windows 10, Windows Security is called Windows Defender Security Center. This is because the built-in security of Windows in S mode automatically prevents viruses and other threats from running on your device.

If you're running Windows in S mode it's streamlined for tighter security, so the Virus & threat protection area has fewer options than those described here.
