This article mainly introduces what files can not be destroyed by computer viruses. What is introduced in this article is very detailed and has a certain reference value. Interested friends must finish reading it!

Computer viruses cannot destroy data and files in CD-ROM because the data and files in CD-ROM are read-only and cannot be written again, so the virus cannot modify it, so it cannot destroy any files.

Computer viruses cannot destroy data and files in CD-ROM.

Because the data and files in CD-ROM are read-only.

Related introduction:

Computer viruses are contagious, concealed, infectious, latent, excitable, expressive or destructive. The life cycle of computer virus: development period, → infection period, → incubation period, → attack period, → discovery period, → digestion stage, → extinction period.

A computer virus is a program, a piece of executable code. Like biological viruses, they have the characteristics of self-reproduction, mutual transmission and activation and regeneration.

Computer viruses have a unique ability to replicate. They can spread quickly and are often difficult to eradicate. They can attach themselves to various types of files, and when they are copied or transferred from one user to another, they spread with the file.

The computer is composed of internal circuits, which can complete all kinds of arithmetic operations with high speed and accuracy. Today, the operation speed of computer systems has reached trillions per second, and microcomputers can also reach more than 100 million times per second, so that a large number of complex scientific computing problems can be solved. For example, the calculation of satellite orbit, the calculation of large dams and 24-hour weather calculation take years or even decades, but in modern society, it can be done in only a few minutes by computer.

Extended data:

The virus is attached to the storage medium floppy disk, hard disk and so on to form the source of infection. The vector of virus transmission is determined by the working environment. Virus activation places the virus in memory and sets a trigger condition, which can be a clock, system date, user identifier, or system communication. When the conditions are ripe, the virus begins to replicate itself in the infected object and carry out various destructive activities.

Virus infection is an important indicator of virus performance. In the process of transmission, the virus replicates itself to the infected object.

There are many kinds of computer viruses, and they are very complicated. According to the different ways and characteristics of computer viruses, there can be many different classification methods. At the same time, the same computer virus can belong to different types of computer viruses according to different classification methods.
