How to Reinstall Norton 360 Without a CD

Updated July 20, 2017

Symantec's Norton 360 security software suite delivers an all-in-one security package for daily computer use. It protects against viruses, worms and hackers, and a single subscription allows up to three of your personal computers to activate and run 360 at the same time. You may install 360 using the CD, but if your computer lacks a CD-ROM drive, you may install the program using the Norton 360 installation package.

Click "Start" button, "Control Panel" and "Uninstall a program."

Click the "Norton 360" application from the list of currently installed programs and then click "Uninstall." The Norton Uninstall Wizard will display onscreen.

Click the "Norton Complete Uninstall" option and "Next" in the Subscription Period Warning window. Windows will remove Norton 360 from your computer. Click "Finish" after the window indicates Norton 360 has been uninstalled successfully.

Restart your computer.

Launch a Web browser of your choice and type "" in the browser's Address bar.

Type your "Email Address" and "Password" when prompted and click the "Sign In" button.

Click "Norton 360" under registered products and write down your product key.

Download the "Norton 360 Installation" file from and save it to your desktop.

Double-click the downloaded installation file to start the installation process.

Click the "User License Agreement" button and place a check in the box next to "Agree & Install." Type your product key in the box and click "Next." Browse for an installation location or use the default Norton 360 install location and click "Next."

Click the "Next" button to begin the installation. Click the "Finish" button, after the status bar fills to 100 per cent, and then restart your computer.
