Norton Security Scan is a free offline scanner that uses Symantec latest virus definitions to scan your computer for the latest security risks and it lets you know how your computer is currently protected from known threats. It will scan and identify if there are existing viruses, worms, spyware, unwanted adware or Trojans residing on your computer. This tool is especially useful if you are using other security software and want to scan with Symantec virus definitions.

Remember that this tool is not intended to be a replacement for continuous, real-time protection from the latest security risks; it will find only the threats; to resolve these security risks and protect your computer from future infections, it is recommended that you install and maintain security software.

To identify the latest Internet risks, Norton Security Scan required latest virus definitions. You can download it from the app. However, when you have not updated the virus definitions for more than a week, Norton Security Scan automatically updates the definitions.
