On October 12, 1989, some British scientists were working at the computers to look for the information they needed. Suddenly they saw a lot of very bright points 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 (恐怖), they found out that most of their stored information was got rid of by computer viruses (病毒) ! Clearly 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 fond of playing tricks. They all had excellent education. They created the viruses just to show their intelligence (才能) . These kinds of computer viruses are named Jerusalem Viruses. These viruses can stay in computers for a long time. When the time comes they will attack the computers by lowering the functions , damaging their normal programs or even getting rid of all the information.
We now come to know that Jerusalem Viruses often attack computers on Friday and that they are spreading (传播) to a lot of computers.
