Windows security black screen

Question

I got malware on my windows 11 PC, and I got rid of it. I checked Windows Defender everything seemed normal. After the malware incident, I reset my PC. Now, when I open Defender, it's just a black screen. I've waited for about 20 minutes, but it remains blank, please help.

Answer 1

Download Farbar Recovery Scan Tool (FRST).

https://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/

Download this Fixlist.txtto the same folder.

• If your computer language is not English, rename FRST64.exe to FRST64English.exe
• Run FRST and press "Scan"
• When that finishes run FRST and press "Fix"
• There should now be three logs created in the folder that FRST is run from, FRST.txt, Addition.txt and Fixlog.txt
• Upload the logs to OneDrive, Google Drive or any file sharing service and post the share link

Note: If you are downloading FRST with Edge, smartscreen will initially block it.

Click on the 3 dots next to the warning and select Keep-> Show more-> Keep anyway.
