Viruses, malware, spyware, phishing and scams

To protect your computer from viruses, you should have virus protection installed. 

From time to time, email messages circulate warning of a potential virus threat, or you might get one about Microsoft sending you money for forwarding an email message, or Microsoft announcing of a serious virus and advising you to tell everyone you know. In the majority of cases, these messages are hoaxes or urban legends that spread like wildfire across the Internet.
