Definition: Norton is a well recognized brand of Internet security software. The publisher is Symantec. Other publishers of the same class of software include Kaspersky, McAffee and AVG. The company offers a wide variety of products for individual users, small and home office owners and larger businesses. Norton sells licenses for multiple computers. A purchaser would select the product that would best suit his or her needs and purchase a license (the costs can vary based upon the number of computers on which the software is to be installed). Once the software is installed on the user or client side the product's features face the Internet and provide protection against online threats. The security application looks for the "signatures" of malware and blocks them.
Its Relevance: The publisher was among the first to produce software to protect against online threats such as viruses, Trojan horses and other malicious software. The company now produces a wide array of products. The company has been in existence since the early days of networking and can be depended upon to deliver a consistent level of service. Working on the Internet without this product or a similar one is ill advised.
