How to Stop Defender on Windows 10 from Automatically Sending Virus Samples to Microsoft

Windows 10’s built-in virus and malware detection security feature will automatically submit samples of infected files to Microsoft. Here’s how to stop it.

Windows Security or Windows Defender on Windows 10 will automatically send samples of detected malware on your PC to Microsoft. This feature helps improve security across the board. It helps Microsoft protect against emerging viruses and ongoing malicious malware threats. However, Microsoft does give you the option to disable this automatic feature. Here’s how to turn off automatic sample submissions of infected files.

Note: For the average user it’s best to keep this option enabled. It helps the company learn about emerging viruses and other malware in the wild. In turn, that helps the company send appropriate virus definition updates out through Windows Update. And Microsoft touts that no personally identifiable information is included with the samples. However, if you are a power user, there might be a reason why you want to turn it off.

Stop Automatic Virus Sample Submissions to Microsoft

If you aren’t comfortable with Microsoft getting virus samples from your PC, you can disable the process. To do that, click on the Start button or hit the Windows Key on your keyboard and click Settings. Or, hit the keyboard shortcut Windows key + I to open the Settings menu.

Settings Windows 10

From the Settings menu click on Update & Security.

Then from the left panel click on Windows Security.

On the following screen, scroll down to the “Automatic sample submission” section and turn off the switch for automatic submissions. You will get a message saying your device is more at risk, but you can just click the Dismiss link to hide that.

That’s all there is to it. Now Microsoft won’t receive automatic file submissions for suspected viruses and other malware from your PC.

You still have the option to manually submit a sample if something is identified as malware on your PC. If you think submission is necessary, click the Submit a sample manually link. That will take you to a Microsoft site where you can upload the suspicious file.

    Sure, that will turn if off. Temporarily. I get reminded EVERY DAY that it is off, and Defender whines about it. I would dearly love to be able to tell windows that yes, I am aware that it is off, and PREFER it that way, and STOP REMINDING ME. But, that doesn’t seem to be possible. This just started happening after a recent update…..
