How do I download or run a program that Windows Defender detects as potentially harmful?

When Windows Defender detects potentially harmful programs, it reports this information to Action Center and alerts you by displaying a notification. If you trust a program that Windows Defender has detected as potentially harmful, you can allow it to run on your computer.

Warning

  • If Windows Defender assigns a severe or high alert level to a program, it's a widespread or exceptionally malicious program or a program that might collect your personal information without your knowledge. These programs can negatively affect your privacy and the security of your computer; they can damage your computer. We strongly advise you don't run these programs on your computer.

  1. Download the program that you want to run.
