Introduction
What do you do when you get a virus or some other sickness? Hopefully, you seek medical attention! If not, is there a chance you are going to share your illness with others around you? Of course there is! Just as we need medical attention to help us overcome a sickness, computers need attention to clear them of any viruses. Just as we spread sicknesses when we neglect to seek the necessary attention, a computer connected to a network can spread viruses to other computers in that network.
