Online threats, such as spyware, phishing, and identity theft, aim to steal important information about you and your business. Some viruses even target databases of a business's customers, allowing attackers to uncover their bank account or credit card numbers. Norton Setup will protect your computer from these threats, but you need to enter a 25 digit product key to unlock all of the program's features. The product key came with your purchase, and Norton requests it to authenticate and activate the software. If you face any trouble dial Norton support number 1866-549-8444.
