What is the principle of the virus and what is the function of the virus?

What is my role? The effect of the virus is harmful to your body, so if you want to have a virus, you must go to the hospital, let the doctor recuperate for you, take some medicine, and the doctor will take care of you.

The biggest feature of viruses is self-replication, and there are many kinds of viruses in terms of classification, and here we will introduce the most popular add-on formulas.

Viruses, which achieve their self-replication purpose by rewriting normal files, increasing them.

Enables a program to copy itself to other programs without affecting the work of other programs themselves, so that it has the ability to continue copying.

Under certain conditions, the first thing to make it have a certain effect, in fact, the first thing can actually be regarded as copying the file, and putting all the functions of the virus source file into the infected.

The main program calls the virus function .

The virus function reads and searches all C files in the same directory.

Find one (infected C file), open it, and read all of this file into an array change.

Recreate a file with the same name (the C file that is dyed by the acre).

The array variable is written back to the infected C file, and at the same time, the header file and the virus function function required by the virus source text are written in a statement.

Open the virus source file and write all the virus function functions to the end of the infected C file.

The new coronavirus is made up of proteins and nucleic acids.

Viruses are made up of two or three components: a non-cellular form consisting of a nucleic acid molecule (DNA or RNA) and proteins, all of which contain genetic material (RNA or DNA, prions composed only of proteins are not viruses); All viruses also have capsids formed by proteins, which are used to encapsulate and protect the genetic material within; In addition, some viruses are able to form lipid envelopes when they reach the cell surface. Viruses are parasitic organic species between living and non-living organisms, they are neither living things nor non-living things, and they are not currently classified in the Five Realms (prokaryotes, protists, fungi, plants, and animals).

It is a piece of DNA or RNA wrapped in a protective shell, and through the mechanism of infection, these simple organisms can use the host's cellular system to replicate themselves, but cannot grow and replicate independently. Viruses can infect almost all living organisms that have cellular structures. Viruses vary in morphology, from simple spirals and icosahedral shapes to composite structures.

Virus particles are about one hundredth the size of bacteria. The origin of viruses is unknown, and different viruses may originate from different mechanisms: some may originate from plasmids (a circular form of DNA that can replicate within cells and be transferred from cell to cell), while others may originate from bacteria.
