Viruses do not generate by chance. the programmer of a virus, known as a virus author, intentionally writes a virus program. writing a virus program usually requires significant programming skills. the virus author ensures the virus can itself, conceal itself, monitor for certain events, and then deliver its payload. "

The answer is 'replicate'. Computer viruses, much like normal viruses, exist only to replicate themselves. The illnesses that people feel when they catch a virus, are to facilitate the spread (replication) of the virus, such as a runny nose and sneezing. Viruses are really just packages of genetic material. Richard Dawkins, in his book 'The Selfish Gene', proposes an alternative view of life on Earth: Organisms, including ourselves, are merely vehicles for their DNA, or a way to ensure their DNA is replicated. 

The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )
