Xiaobian to share with you what the characteristics of computer viruses are, I believe most people do not know how, so share this article for your reference, I hope you have a lot of harvest after reading this article, let's go to understand it together!

The six characteristics of computer viruses are: 1. Parasitic; computer viruses parasitize in other programs, and when this program is executed, the virus plays a destructive role. 2) destructive. 3. Infectious. Latency: Some viruses are like time bombs, and when they attack is pre-designed. 5. Concealment. 6. Executability.

A computer virus is a code inserted into a computer program by a programmer to destroy computer functions or data, which can affect the use of a computer and can replicate itself.

Computer virus is artificially created, destructive, infectious and latent, to computer information or systems play a destructive role in the program. It does not exist independently, but is hidden in other executable programs. After the virus in the computer, it will affect the running speed of the machine, and the system will be destroyed if it is serious; therefore, the virus will bring great losses to the user. Usually, we call this destructive program a computer virus.

Six Characteristics of Computer Viruses

1. Parasitic:

Computer viruses have parasitic characteristics. Computer viruses need to parasitize in the host in order to survive, in order to better play its function, destroy the normal function of the host. Usually, computer viruses are parasitic in other normal programs or data, and on this basis, they use certain media to spread. In the actual operation process 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 continuously assist and modify the host computer files, so that its destructive effect can be exerted.

2. Destructive:

After computer poisoning, it may cause normal programs to fail to run, delete files in the computer or be damaged to varying degrees. Destroy boot sector and BIOS, hardware environment destruction.

3. Infectious:

Computer virus infectivity refers to the computer virus by modifying other programs to its own copies or variants infected to other non-toxic objects, these objects can be a program can also be a component of the system.

4. Latency:

Some viruses are like time bombs, with pre-programmed timing. For example, the Black Friday virus was imperceptible until a predetermined time. When the conditions were met, it exploded and destroyed the system.

5. Concealment:

Computer virus has very strong concealment, can be checked out by virus software a few, concealment computer virus from time to time, capricious, this kind of virus is very difficult to deal with.

6. Executability

A computer virus, like any other legitimate program, is an executable program, but it is not a complete program, but a parasite on other executable programs, so it enjoys all the power that programs can get.

The above is "what is the characteristic of computer virus" all content of this article, thank you for reading!
