How to Reinstall Norton 360 After a Reformat

Updated August 16, 2017

One of the most important things a computer user can do is to ensure that his PC is protected against threats from the Internet. One of the more popular programs available is Norton 360, a protection suite that manufacturer Symantec calls "ultimate protection and peace of mind against digital dangers." Norton 360 claims to offer protection against viruses, spyware, Trojan horses, worms, bots and rootkits. If you've had to reformat your hard drive, you may be looking to reinstall Norton 360. A few steps will have your Norton 360 back on the job in short order.

Locate your Norton 360 installation disk. Download the Norton 360 installation file from the Symantec website if you don't have an installation disk (See Resources).

Locate your Norton 360 Product Activation key. Contact Symantec to get a copy of your key, if you can't find yours.

Insert the Norton 360 installation disk or double-click the "Norton 360" installation program on the desktop. Close all other open programs to prevent any conflict.

Click the "Install Norton 360" option. Read the "User Agreement" and click "I Agree." Enter your "Product Activation" key and click "Next" to begin reinstalling the program.

Wait for the installation process to complete. This may take 5 to 30 minutes to complete.

Type in your login details for Norton and click "Next."

Click "Finish." Allow the "Quick Scan" to run to complete the reinstall process.
