Norton isn't designed as a portable application. However, Symantec's Norton Security Scan is a scaled-down version of the full Norton anti-virus that scans for viruses, malware, spyware and adware. While it can remove some viruses, it may not be able to remove all detected problems. This version of Norton can be placed on a USB drive for portable virus scanning and troubleshooting by your businesses' IT department.


Download Norton Security Scan to your computer (See Resources).


Double-click the downloaded file and follow the prompts to install. Accept all defaults and make a note of the directory where Norton Security Scan installs.


Insert your USB drive into your computer.


Open Windows Explorer and navigate to the directory where Norton Security Scan installed. By default, the path is “C:\Program Files\Symantec.”


Right-click the “Norton Security Scan” folder and click “Copy.”


Open your USB drive in Windows Explorer and right-click inside the window. Click “Paste” to copy the Norton Security Scan directory to your USB drive.


Insert the USB drive into any computer and double-click the “nss.exe” file to launch Norton Security Scan on an employee's computer.

Things Needed

  • Norton Security Scan
  • Empty USB drive


  • Using an empty or formatted USB drive prevents any conflicts on the drive itself when running Norton Security Scan. It also prevents any important files from being infected if an employee's computer does have a virus.


  • If a virus is detected, you may need to use a different anti-virus solution to remove it. Norton Security Scan as a portable application may not be able to remove all virus related problems. You should boot the employee's infected computer in Safe Mode and run the company's main anti-virus software on the system to remove any remaining traces of the infection.
  • Norton Security Scan does not provide live protection. It only scans and detects when you manually run the program.
