norton.com/setup

I am using an HP laptop for my official tasks. I am working from home to complete official tasks. I want to protect my laptop from virus attacks, so I want to install Norton antivirus software on my laptop. Due to virus attacks, my laptop may corrupt. So I want to protect my HP laptop, my important data, and files. I want to install Norton antivirus software using Norton.com/setup. I am a new user, and so, I have to create an account with Norton.com/setup. After creating the account, I have signed into my account on norton.com/setup. I have clicked on the Norton setup window and choose the Transfer Norton setup button. After that, I have to enter the Norton product key that you have bought. After this step, I am facing problems to complete the next step. I am a new user, hence I don’t have much experience with the installation process of Norton antivirus using Norton.com/setup. So anyone can help me to install Norton antivirus using Norton.com/setup?
