On October 12, 1989, some Chinese scientists were looking at the computers to look for the information they needed. Suddenly they saw a bright spot crossing the computers’ screens. 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. To their horror, they found that almost all their stored information was got rid of by computer viruses. Obviously all these computers had been infected by computer viruses.
It was said that computer viruses were made by a group of young men fond of playing tricks. They all had excellent education. They created viruses just to show that they were clever. This kind of computer viruses named Jerusalem 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 Fridays and that they are spreading to a lot of computers. Among the’ countries that suffered from computer viruses lately are Britain, Australia, Switzerland and the US. But till now, how to get rid of the terrible viruses remains a problem.
