Windows 10 has divided the protection level of Windows Defender into two main groups. One is real-time protection and the second is cloud-based protection. Genuinely, these two protections are made up for the security of your computer.
Sometimes there you get into a situation where your Windows Defender is not up to date and you get into a situation where you come across a malicious file. When the cloud protection will be ON, it will send the file to Windows Defender cloud security services to understand the file’s behavior. You can also this option off by following the below steps.
Click on the start menu and start typing Windows Security, Click on the Open link to open Windows Security.
On the left corner, click on the gear icon to access Windows Security settings.
In settings windows, click on Manage notifications under Notifications.
In Notification Settings, under Virus & threat protection notifications, click on Virus & threat protection settings. You can also access the same settings by clicking on Virus & threat protection from the left menu and then click on Manage settings under Virus & threat protection settings.
Toggle the on option under cloud-delivered protection to turn off the cloud-delivered protection. Toggle the same option to turn on the cloud-delivered protection.
Once the cloud-delivered protection is turned on, make sure that we need to turn on Automatic sample submission. The automatic sample submission will allow Windows Defender to send the malicious files to Windows Defender Cloud protection.
