Windows Defender according to the Microsoft it has evolved a lot in recent builds of Windows. Of course, tests by independent companies show that software always in the last positions. Microsoft, however, continues to tirelessly praise it. Today the company has published an in-depth analysis which details how she can block her super software, completely unknown malicious software.
Microsoft reports that Windows Defender only needs 10 seconds (the maximum) to analyze a malware-infected file that has never been released before. Microsoft antivirus will not only protect this user but will submit the infected sample to protect everyone who uses Windows Defender.
The company emphasizes that the Cloud is what makes Windows Defender react so quickly and effectively in the case of some unknown malware, explaining that while it inspects archives for potential infections, while also preventing potential malicious behavior on the systems of all Cloud users.
As described in the infographic you can see below, when suspicious files are found, they are submitted to the cloud for a analysis in depth. Once the cloud decides that the file is unknown, it requests a sample for further analysis. 
The file is automatically uploaded to Microsoft cloud systems that process it using mechanical learning.
Cloud then creates a signature and sends it to the client while the Windows 10 system blocks the file and the cloud begins to protect all other users of the operating system.
The whole process is completed in less than 10 seconds, and according to Microsoft offers complete protection as soon as the cloud resolution is activated by the "Settings" application.
"When enabled, Windows Defender AV locks suspicious files for 10 seconds by default, asking Windows Defender Cloud AV protection service. "Administrators can configure Windows Defender AV to extend the time period by up to a minute to give the cloud time to further analyze and apply additional techniques to detect new malware."
This feature is only available in the latest version version of the Windows 10 Creators Update, which will be released in September.
