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.

Mr. Peter Johnson, aged twenty-three, battled for half an hour to escape from his trapped car yesterday when it landed upside down in three feet of water. Mr. Johnson took the only escape route—through the boot(行李箱).

Mr. Johnson’s car had finished up in a ditch(沟渠) at Romney Marsin, Kent after skidding on ice and hitting a bank. “Fortunately, the water began to come in only slowly,” Mr. Johnson said. “I couldn’t force the doors because they were jammed against the walls of the ditch and dared not open the windows because I knew water would come flooding in.”

Mr. Johnson, a sweet salesman of Sitting Home, Kent, first tried to attract the attention of other motorists by sounding the horn and hammering on the roof and boot. Then he began his struggle to escape. Later he said, “It was really a half penny that saved my life. It was the only coin I had in my pocket and I used it to unscrew the back seat to get into the boot.

It took ten minutes to unscrew the seat, and a further five minutes to clear the sweet samples from the boot. Then Mr. Johnson found a wrench and began to work on the boot lock. Fifteen minutes passed by. “It was the only chance I had. Finally it gave, but as soon as I moved the boot lid, the water and mud poured in. I forced the lid down into the mud and jumped out of the ditch.”

 His hands and arms cut and bruised(擦伤), Mr. Johnson got to Beckett Farm nearby, where he was looked after by the farmer’s wife, Mrs. Lucy Bates. Huddled in a blanket, he said, “That thirty minutes seemed like hours.” Only the tips of the car wheels were visible, police said last night. The vehicle had sunk into two feet of mud at the bottom of the ditch.
