This article will explain in detail what the computer virus generally refers to. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

What is correct in the description of computer viruses is that "anti-virus software must be upgraded with the emergence of new viruses to improve the function of checking and killing viruses." computer viruses are destructive programs with no logic errors themselves. The computer itself is not immune to computer viruses; the characteristics of computer viruses are parasitic, destructive, contagious, latent and hidden.

Computer virus is a destructive program, there is no logic error in itself, and the computer itself is not immune to computer viruses. The characteristics of computer viruses are parasitic, destructive, contagious, latent and hidden.

Computer viruses are artificial, destructive, contagious and latent programs that destroy computer information or systems. It does not exist independently, but is hidden in other executable programs. After the virus in the computer, the light will affect the running speed of the machine, and if it is serious, the crash system will be destroyed; therefore, the virus will bring great losses to users. Usually, we call this destructive program a computer virus.

According to the existing media classification, computer viruses can be divided into three types: guided virus, file virus and mixed virus; according to the link mode, they can be divided into three types: source virus, embedded virus and operating system virus; according to the system classification of computer virus attack, it can be divided into attack DOS system virus, attack Windows system virus, attack UNIX system virus. Today's computer viruses are constantly pushing through the old and bringing forth the new, including some unique new viruses that are temporarily unable to be classified according to conventional types, such as Internet viruses (spread through the Internet, some carry more and more virus data), e-mail viruses and so on.

Computer virus is recognized as the number one enemy of data security. Since 1987, computer virus has been paid more and more attention all over the world. Computer virus was first discovered in China in 1989. At present, the new virus is developing in the direction of more destructive, more secret, higher infection rate, faster spread speed and so on. Therefore, we must deeply study the basic knowledge of computer viruses and strengthen the prevention of computer viruses.

About the computer virus generally refers to what is shared here, I hope the above content can be of some help to everyone, can learn more knowledge. If you think the article is good, you can share it for more people to see.
