This article mainly introduces the characteristics of computer viruses, which can be used for reference. I hope you can learn a lot after reading this article. Let's take a look at it.

The five characteristics of computer viruses are: 1. Parasitism; computer viruses need to be parasitic in the host to survive in order to better play their functions and destroy the normal function of the host. 2, contagious; can invade the computer through U disk, network and so on. 3. Latent nature. 4. Concealment. 5. Destructive.

Computer virus (Computer Virus) is a group of computer instructions or program codes that programmers insert into computer programs that destroy computer functions or data, can affect the use of the computer, and can copy themselves.

Five characteristics of computer viruses:

1. Parasitism

Computer viruses also have parasitic characteristics. Computer viruses need to be parasitic in the host in order to survive, to better exert their functions and destroy the normal function of the host. In general, computer viruses are parasitic in other normal programs or data, and on this basis, a certain medium is used to achieve transmission. In the actual operation of the host computer, once a certain setting condition is reached, the computer virus will be activated. With the start of the program, the computer virus will constantly assist and modify the host computer files, so that its destructive role can be brought into full play.

2. Infectivity

One of the major characteristics of computer viruses is contagious, which can invade the computer through U disk, network and other ways. After the invasion, it is often possible to spread the virus, infect the uninfected computer, and then cause a large area of paralysis and other accidents. With the continuous development of network information technology, the virus can achieve a wide range of malicious intrusion in a short period of time. Therefore, in the security defense of computer viruses, how to face the rapid virus infection has become an important basis for effective defense against viruses, and it is also the key to build a defense system.

3. Latent property

Some viruses are like ticking time bombs, and when they attack is designed in advance.

4. Concealment

Computer viruses have strong concealment, some can be detected by virus software, some can not be detected at all, and some are sometimes hidden and changeable, which is often difficult to deal with.

5. Destructive

After the computer is poisoned, it may cause the normal program not to run, delete the files in the computer or be damaged to varying degrees.

Thank you for reading this article carefully. I hope the article "what are the characteristics of computer viruses" shared by the editor will be helpful to everyone? at the same time, I also hope that you will support and pay attention to the industry information channel. more related knowledge is waiting for you to learn!
