We’ve updated your protection

We’ve improved the cloud-based protection and automatic sample submission features included in Windows 10 so that Windows Security can respond to new threats faster. In most cases, Windows Security uses cloud-based protection to detect and block threats the very first time it encounters them. In some cases, Windows Security will use the cloud to analyze the suspicious program. This analysis helps Windows Security learn about new threats, so it can respond with protection much faster than on earlier versions of Windows.

How do I know if I’m protected?

By running Windows Security with cloud-delivered protection and automatic sample submission turned on, you can rest assured that you’re receiving the very highest level of protection from the latest threats. That’s it!

Updates to Windows Security settings

Thanks to your feedback, we’ve made some changes to the Windows Security settings to help make securing your PC as easy as possible.

Offline scan 

Run an offline scan to find and remove malware that can’t be found with a normal scan. To run an offline scan in Windows Security, select Virus & threat protection, and then under Current threats, select Scan options > Windows Defender Offline scan > Scan now.
