Security techniques and technology — physical security, user account security, server security, and locking down your servers — are child’s play compared with the most difficult job of network security: securing your network’s users.

Viruses are one of the most misunderstood computer phenomena around these days. What is a virus? How does it work? How does it spread from computer to computer?
What is a virus?
Make no mistake — viruses are real. Now that most people are connected to the Internet, viruses have really taken off.
