随着互联网时代计算机病毒技术的发展,病毒的感染方式与过去相比发生了翻天覆地的变化。无论是数量上,还是速度上,病毒对于计算机安全的危害远非昔日可比。世界上第一个病毒流传到中国,用了差不多两年的时间。在此之后的三年里,病毒总数的增长也不过几十种。然而,随着计算机技术的发展,到1998年底,全世界的病毒总数,已达20000多种。而更可怕的是,在其后1年多的时间里,这个数字竟然翻了一番。计算机病毒不仅是在数量上增长,在传播速度上的增长更是令人膛目结舌:1999年3月爆发的“Melissa”在17个小时里感染了300多家企业的10万
With the development of computer virus technology in the Internet era, the virus has changed dramatically in comparison with the past. In terms of quantity and speed, the virus’s harm to computer security is far from comparable. The world’s first virus spread to China and took almost two years. In the three years since then, the total number of viruses has grown by only a few dozen. However, with the development of computer technology, by the end of 1998, the total number of viruses in the world had reached more than 20,000 kinds. What is even more frightening is that in the more than one year after that, the figure has actually doubled. Not only is the number of computer viruses increasing, the growth in the speed of transmission is even more striking: the “Melissa” that broke out in March 1999 infected 100,000 of more than 300 companies in 17 hours.
