Windows 10’s May 2019 Update brings a new “tamper protection” feature to Windows Security, also known as the Windows Defender antivirus. Tamper Protection is off by default, and Windows Security says “your device may be vulnerable” unless you enable it.
What Is Tamper Protection on Windows 10?
According to Microsoft, Tamper Protection ” helps prevent malicious apps from changing important Windows Defender Antivirus settings, including real-time protection and cloud-delivered protection.” In other words, it makes it more difficult for malicious software running on your PC to disable real-time antivirus protection and other features.
You can still configure settings yourself via the Windows Security app. In fact, once you enable Tamper Protection, you shouldn’t notice anything different. That’s why we recommend enabling it.
Note that Tamper Protection only applies to Windows Security settings. If you’re using a third-party antivirus, it won’t protect that antivirus’s settings. Some third-party antivirus programs have similar built-in “tamper protection” features to protect their own settings, too.
Protected settings include real-time protection, cloud-delivered protection, IOfficeAntivirus (IOAV), behavior monitoring, and removing security intelligence updates. Applications can’t adjust these settings using mobile device management and other enterprise solutions, command-line options, group policy, the Windows registry, and various other methods with the protection enabled.
How to Enable Tamper Protection
This setting is included in the Windows Security application. To open it, search your Start menu for Windows Security and click the “Windows Security” shortcut, double-click the Windows Security shield icon in your notification area (system tray), or head to Settings > Update & Security > Windows Security > Open Windows Security.
