The fixlist will remove the malware and run the System File Checker. You will then need to perform a repair installation to restore Windows Defender and its services.

  • Save Fixlist.txt to your Downloads folder.
  • Close any apps with unsaved work.
  • Run FRST64.exe and click "Fix".
  • The computer will reboot to complete the procedure.

Please upload Fixlog.txt

For the repair, go to: https://www.microsoft.com/en-au/software-download/windows10

  • Just below Create Windows 10 installation media click on Download tool now
  • Run MediaCreationTool22H2.exe, accept the license terms then select Create installation media.
  • Use the recommended options then for Choose which media to use, select ISO file.
  • Once downloaded, right click the ISO and select mount, then launch setup.exe
  • Click on Change how Setup downloads updates and select the option Not right now.

** If the option to Keep personal files and apps is greyed out, abort the installationenter image description here

You will have active malware running as a result. Please provide Farbar Recovery Scan Tool (FRST) logs for analysis.

Note: If you are using Edge or Chrome, SmartScreen may initially block the download. Click on the three dots next to the warning and select Keep => Click the Delete drop arrow => 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, Google Drive or gofile.io
  • Post the share link.
