On May 21, 2000, some American scientists were working at the computers to look for information they needed . Suddenly they saw a lot of very bright red spots crossing the computers’ screens. At the same time the computers were working much slower. To find out what was happening they stopped their work to check some parts of the computers. To their horror, they found out that most of their stored information was got rid of by computer viruses (病毒). Obviously all these computers had been infected by computer viruses. It is said that the computer viruses were made by two or three Philippine young men fond of playing tricks. They all had excellent education. They created the viruses just to show their intelligence. The kind of computer virus is named I Love You Virus. This virus can hide in computers for long. When the time comes they will attack the computers by lowering the important functions, damaging their normal programs or even getting rid of a great deal of information which operators of the computers often use or store, what’s worse, it still can reproduce itself in great quantities within a short time. We come to know that “I Love You” Virus often attacks computers on Mondays and that it is spreading to many computers in the world. Among the countries that suffered computer viruses last year are Britain, Australia, Switzerland and the USA. Those who made the computer muses have been found out slowly and carefully. But till now, how to get rid of the terrible viruses remains a problem. 1.When the viruses attack the computers, the computers will work _______.
