Life as we know it today would be handicapped without computers. From basic communication, finances and even medical science, computers control just about everything that life in a modern society depends upon. In the ideal world man would respect such power and work towards bettering it to progression as a civilisation. Unfortunately that ideal world does not exist which is why great breakthroughs are often followed by people who are hell-bent on bringing it all down. These people only see weaknesses of an innovation in technology and will go any lengths to exploit it, simply because they can. These are the people who create viruses.
A computers virus can be defined as an executable program that is capable of infecting other computers programs by modifying them to include a copy of itself. Just the way people can spread the common cold by being in contact with other people, a computer virus comes in contact with other programs to 'infect' them. By infecting programs, the virus is capable of spreading through n entire network of computers, infecting every machine that's incapable of protecting itself. While doing so, it could do a world of damage to your computers, which could cost you dear. The damage could consist of important files destroyed, corrupted data, slowing down of the infected computers, interrupted of unexpected closing of important programs, of it could be any or all of these; and chances are you won't realise that your computer is hit by a virus until it's much too late.
Viruses have grown in number and evolved in nature over the past decade. Before that, it was quite all right to have a basic and even outdated antivirus program on your computer, which would scan floppies or CDs. That simple task would qualify as protection at the time, but we now need active antivirus programs, constantly running, checking every file you download or execute.
