The Norton Power Eraser tool is compatible with computers running Microsoft Windows operating systems only. It does not work with computers running on Mac OS, WinPE, Android, and iOS.

Norton Power Eraser uses aggressive methods to detect threats, and there is a risk that it can select some legitimate programs for removal. You should carefully review the scan results page before removing files.

Download Norton Power Eraser and run a scan

  1. Download Norton Power Eraser.

  2. Press Ctrl + J key, to open the Downloads window in your browser, and double-click the NPE.exe file.

    If the User Account Control window prompts, click Yes or Continue.

  3. Read the license agreement, and click Accept.

    Norton Power Eraser checks for and prompts to download the new version if available.

  4. In the Norton Power Eraser window, click the Scan for Risks icon.

  5. By default, Norton Power Eraser performs a Rootkit scan and requires a system restart. When you see a prompt to restart the computer, click Restart.

    If you do not want to include the Rootkit scan, go to Settings, and uncheck the option Include Rootkit Scan (requires a computer restart).

  6. Wait for the scan to complete.

Fix the risks

  1. When Norton Power Eraser completes the scan, it displays the scan results. The items that Norton Power Eraser considers as risks, display the status as Bad and recommended action as Remove or Repair. The items that require further review display the status as Unknown.

  2. Depending on your situation, do one of the following:

    • If you see No Risks Found, Norton Power Eraser did not detect any risks on your computer, click OK to exit.

    • If you see any files that are listed as Bad, the Remove check box under Action is checked automatically. It is recommended to remove these files. If the Repair check box under Action is checked, then these files will be repaired after the restart.

    • If you see any files that are listed as Unknown, for each of these files, click the cloud icon next to it. It sends the file to a Norton server and scans it using the traditional signature-based detection engines.

      • If the Cloud Scan result shows Bad for any file, click the Remove check box.

      • If the Cloud Scan result shows Unknown, do not click the Remove check box. The file may not be a threat, and needs further analysis.

Norton Power Eraser comes with a Cross OS Undo feature with which you can undo a repair session by booting into the computer using a different operating system.

    1. Start your computer using a different operating system.

    9. Review the fixes that are performed in the selected repair session. Select the files that you want to restore, and then click Undo.
