Why is Windows Security Showing a Blank White Screen?

Before troubleshooting the Windows Security issues, it’s essential to know why the Windows Security app shows a blank white screen in detail. Here are the possible reasons that lead to Windows Security issues

• Third-Party Antivirus Interference

This is the prominent reason the Windows Security app shows a blank screen issue. The Windows Security app is set to turn off automatically once it detects third-party security software.

However, sometimes, the Windows Security app may fail to detect your third-party antivirus program, leading to conflict. This conflict often triggers Windows Security to show a blank screen issue.

• Problem with the Windows Security

Like all programs, the Windows Security app on your PC can encounter problems. When it does, it may fail to open or show a blank screen.

When the Windows Security app encounters problems, it can also force-shut down your computer while running a Full Scan.

Although very rare, malware attacks can sometimes pass through Windows Security or other third-party security apps that you use and turn them off.

If the system files are corrupted, you will have issues using your computer. You may occasionally get BSOD or face problems like the Windows Security app not opening or showing a blank screen.
