Norton Security Scan is a free program distributed by Symantec. It scans the computer for certain types of viruses and malware, but does not remove them from the system. To remove malware, a full-featured security program must be installed. If you have used Norton Security Scan and decided that you prefer another security product, or have discovered a virus, remove it from your system to make room for a full-featured virus removal program.

Skill level:
Moderately Easy


  1. 1

    Click the "Start" button, then click "Control Panel."

  2. 2

    Launch the "Add or Remove Programs" icon in Windows XP or the "Programs and Features" icon in Windows Vista and 7.

  3. 3

    Click "Norton Security Scan," then click "Change/Remove" or "Uninstall." When the uninstall utility launches, click "Next," then click "Restart Now." When the computer restarts, Norton Security Scan should be removed from the computer. If it is not, continue to the next step.

  4. 4

    Launch the Windows Task Scheduler from the "Start" menu.

  5. 5

    Right-click the task "NSSStub" and click "Delete." If you are running Windows Vista or 7, click "Task Scheduler Library" on the left side of the screen to locate NSSStub. Click "Yes" in the confirmation box that appears, then close the Task Scheduler.

  6. 6

    Press the Windows logo and "R" keys at the same time to display the Run dialogue. Type "regedit" in the dialogue box and press "Enter." The registry editor appears.

  7. 7

    Click the "+" or triangle-shaped icons on the left side of the screen to navigate to "HKEY_LOCAL_MACHINE," "Software," "Microsoft," "Windows," "CurrentVersion" and "RunOnce." Click the RunOnce folder.

  8. 8

    Look for an entry on the right side of the registry editor window called NSSInstallation. If you find it, right-click it and click "Delete."

  9. 9

    Click "Yes," close the registry editor and restart the computer. If Norton Security Scan is still present, remove it from the "Add or Remove Programs" or "Programs and Features" menu a second time. Following this, Norton Security Scan should no longer appear on the computer.
