On October 12, 1989, some Chinese scientists were working at the computers to look for the invention they needed. Suddenly they saw something bright crossing the computers’ screens, and there was so much! At the same moment the computers were working much slower. To find out what was happening they stopped their work to check some parts of the computers. Much to their surprise, they found out that most of their stored information was cleared up by computer viruses (病毒)! What was worse, all these computers had been infected (感染) by computer viruses.

It is said that the computer viruses were made by a group of young men who all had good education. They made the viruses just to show their intelligence (才能). These kinds of computer viruses are called Jerusalem Viruses. These viruses can stay in computers for a long time. When the time comes they ill attack the computers by slowing down the function (功能), damaging (破坏) their normal programs or even clearing up all the information.

We now come to know that Jerusalem Viruses often attack computers on Friday so they are also called “Friday Viruses” and that they are spreading (传播) to a lot of computers. Among the countries that suffered (遭受) computer viruses are Britain, Australia, Switzerland, the United States of America, and some other countries. But till now, how to clean up the terrible viruses is still a problem.
