Blank screen when opening Windows Security...

Question

Hello, My name is Aatiz.

I've been trying lots of ways to fix this problem in my computer. This came when i installed a game and it needs to disable antivirus, so i disabled it with the application in the folder of the game. After a long time, i uninstalled it and then try to enable the antivirus with the same app, it is not working. i installed other antivirus to clear any viruses or malware to fix it, but still after 6 months, it not still working. Please give me a way to fix this...

Answer 2

It's likely that Windows Defender's binaries and registry service configurations have been deleted. The best way to fix this is with a repair installation.

To thoroughly check for malware before the repair, please run a scan with Farbar Recovery Scan Tool (FRST) and share your logs.

Note: If you are using Edge, SmartScreen may initially block the download.

Click on the three dots next to the warning and select Keep => Show more => Keep anyway.

• If your computer's language is not English, rename FRST64.exe to FRST64English.exe
• Run the tool, leave the default settings, and press Scan.
• Zip the logs, FRST.txt and Addition.txt, then upload to a cloud storage service like OneDrive or Google Drive.
• Post the share link.
