Time of discovery of my country's first computer virus

#In 1988, our country discovered the first case of computer virus - the small ball virus. The virus will attack when the system clock is at half o'clock or on the hour and the system is performing a disk read operation.

When the virus attacks, a small ball will appear on the screen, beating constantly and moving in an approximate sinusoidal shape. The English letters that the ball touches will be completely cut off, and the Chinese characters that the ball touches will be cut off in half or entirely, and tab characters may also be left behind.

## When the small ball virus just appeared, there was no anti -virus software in China, and some programmers used Microsoft's software defect debugging procedures. DEBUG is used to track and remove viruses, which has become the earliest and most original manual anti-virus technology.

Since the first floppy disk virus ball virus appeared in China, with the continuous growth of new viruses, China's anti-virus technology has begun a long process of exploration.

In July 1989, the virus research team of the Supervision Division of the Computer Management Supervision Bureau of the Ministry of Public Security launched China’s earliest anti-virus software, Kill version 6.0. This version could detect and remove viruses that appeared in the country at that time. of six viruses.

With the gradual popularization of Windows 95 and Windows 98 operating systems, computers have begun to enter the era of visual windows. Data exchange between computers and the outside world has become more and more frequent, and computer viruses have begun to invade from various entrances.

In addition to floppy disks, CDs, hard disks, online neighbors, emails, network downloads, registry, etc. may become channels for virus infection.

In 1999, Jiangmin Company was the first to successfully develop real-time virus monitoring technology, breaking through the single anti-virus concept of anti-virus software for the first time and creating a new era from "anti-virus" to "anti-virus".

Since then, anti-virus software has begun to get rid of the concept of an anti-virus disk, and an installation version has appeared for the first time.

Since the year 2000, the Internet has been developing rapidly, and terms that were originally unfamiliar to computer users, such as worms, Trojans, spyware, and adware, have become familiar.

In 2000, there were less than 60,000 types of viruses; in 2008, there were more than 1 million types of computer viruses.

Faced with the exponential increase in the number of viruses, unknown virus active defense technology emerged as the times require. It also created a new era of active defense against unknown viruses in the antivirus industry.
