I want to protect my computer system from various types of viruses like spyware, malware, and Trojan. I want to keep the back up of my important data, necessary files and folders, so I want to install Norton antivirus on my computer system. I want to install this security product through norton.com/setup. But I don’t have sufficient knowledge to set up Norton antivirus on my computer system. Can you guide me to set up Norton antivirus through norton.com/setup simply?
