On Oct. 12, 1989, some Chinese
scientists were working at the computers to look for the in- formation they
needed. Suddenly they saw a lot of very bright spots crossing the
computer’s 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 out that most of their
stored information was got rid of by computer viruses (病毒). All these computers
had been infected by computer viruses. It is said that the computer viruses were made by a group of young men fond of playing tricks. They all have excellent education. They created the viruses just to show their intelligence. These kinds of computer viruses are named Jerusalem Viruses. These viruses can stay in computers for a long time.
