Internet security involves protecting a computer's Internet account and files from the intrusion of an outside user. Internet users today are familiar with companies like Symantec (Norton Anti-Virus) and McAfee, who offer Internet security products to protect against computer viruses, as well as to protect secure firewalls and to protect against spyware.
