In today's world, we rely on computers as never before.They are used for everything from ordering a pizza to running hospitals and military defense systems.Banking and credit card information is stored and accessed by computers.So what happens when a computer gets infected with a virus?One effect is that people's access to their e-mail accounts is cut off.A more serious possible consequence is that billions of dollars could be lost.
A virus is a computer program that copies itself onto other programs and infects them.Similar to an easily spread disease, a computer virus goes from computer to computer, either adding to or changing the tasks a program is designed to do.
The first computer viruses were created in the mid '80s and had varying effects.Some caused files to be deleted, or made the letters on the screen appear to fall off.Others displayed a specific message once the computer was turned on.
Viruses today are much more widespread and dangerous than ever before.Perhaps the most damaging to date has been the“I Love You”virus.“I Love You”appeared in May 2000 and has possibly been the most destructive virus in terms of monetary loss.
The virus is released when an attachment to a fake e-mail message is opened.By changing the names of files on computers,“I Love You”makes them difficult to access.It also searches for important personal information, including passwords, which it sends to a web site for others to see.
It is estimated that more than 45 million people in 20 countries have had their computers infected by the“I Love You”virus.Some say the cost of repair and lost business has been more than US$10 billion.
If you own a computer, it is important to keep it in good health by installing an anti-virus program.If updated frequently, it will protect your e-mail access--not to mention your wallet.

Once upon a time the colors of the world started to quarrel.Green said,“Clearly I am the most important.I am the sign of life and hope.I was chosen for grass, trees and leaves.Without me, all animals would 1 .”
Blue interrupted,“You only think about the 2 , but consider the sky and the sea. 3 the water that is the basis of life and drawn up by the clouds from the deep sea.Without my peace, you would all be 4 .”
Yellow chuckled(笑道),“You are all so serious.I bring laughter, fun, and 5 into the world.”
Orange started next to blow her trumpet,“I am the color of health and strength.I may be 6 , but I am precious for I serve the needs of human life.When I fill the sky 7 , my beauty is so striking that no one gives another 8 to any of you.”
Red could stand it 9 and he shouted out,“I am the ruler of all of you.I am the color of danger and of bravery.I am willing to 10 truth.I am also the color of passion and of love.”
Then came Purple and Indigo(深蓝)….
The colors went on boasting, each convinced of his or her own 11 .Their quarreling became louder and louder.Suddenly there was a startling flash of bright lightening thunder.Rain started to pour down 12 .The colors crouched(蜷缩)down 13 , drawing close to one another for comfort.
In the midst of the clamor(叫嚷), rain began to speak,“You foolish colors, fighting 14 yourselves, each trying to dominate 15 .Don't you know that you were each made for a special purpose, 16 ?Join hands with 17 and come to me.”
Doing as they were told, the colors 18 and joined hands.They formed a colorful rainbow.From then on, whenever a good rain 19 the world, a rainbow appears in the sky.They remember to 20 one another.
