Visit the official Norton website and create a new account if you don't have one. Sign in if you already have an account via Norton.com setup login, and a pop-up window will appear with a link to install the software. Agree to terms and conditions before downloading the software. After the download, you can easily install Norton's antivirus software by opening the downloaded file and following the instructions on the screen. Once the installation process is done, set a strong Norton account password for keeping your account safe. These were the steps that can help you in recovering Norton's account when followed carefully.
