Fortunately, with the right tools and techniques, you can eradicate the malware without resorting to a complete system wipe.

Run Windows Defender in Safe Mode

• Restart your computer in safe mode by booting while pressing the F8 key.
• Log in to your account and open the PowerShell as an administrator.
• Run the command 'Windows Defender' to start a full scan.
• Wait for the scan to complete and review the results.

Use Additional Anti-Malware Tools

If the previous steps do not resolve the issue, it may be necessary to use additional anti-malware tools.
