    Like several antivirus vendors, Symantec provides a Norton free online virus scan to check if a computer is infected with malware, viruses, Trojans, worms, keyloggers, spyware, adware, potentially unwanted programs, and rootkit. The free online virus scan by Norton does not remove detected threats but will help to verify if your resident antivirus protection has missed any threats.

    What Does Symantec Security Scan Do?

    The free online security scan offered by Symantec will test your PC's exposure to a wide range of online threats including:

    • Security Scan - This option will test whether your PC is vulnerable to intruders and hackers. It will also test Windows for vulnerabilities, if your PC is safe from Trojan Horse attacks or if you have an antivirus program, and if the antivirus detection signature of the antivirus is up-to-date.
    • Virus Detection - This option allows you to run the free online virus scan by Symantec. It also identifies any detected items not fixed or removed by Norton online scan. You will need to get another virus removal tool or buy Norton Antivirus program to proceed in removing any malware.

    System Requirements for Using Norton Security Scan

    You need to use Internet Explorer 5.0 and higher to use Norton online virus check. Firefox users can also use the service but it will only run the Security Scan and not a virus detection because the online scanner requires ActiveX to run the online virus scanner.

    Note to Vista and Windows 7 users: You do not need to disable the Protected Mode in IE7 or IE8 to use Norton online virus or security scans. A UAC prompt will be displayed when Symantec's ActiveX control is ready to install, which allows the scanner to run with administrative permission to scan what it has to check or access in your PC.
