Please answer in detail which major computer viruses belong to

It belongs to computer programming, and the so-called computer virus is actually some program that is written, so that it actively executes the program or stimulates the program to run when the user performs certain operations, so as to achieve the purpose of controlling the user's computer or stealing user information.

Generally speaking, Trojans steal user information or control other people's computers, while some worms send data packets to users or send data packets to the outside world to achieve the purpose of clogging the network.

Here are a few examples:

Trojan horse: stealing user information, which can be used to steal passwords such as user bank and QQ (of course, not only for these purposes).

Worm: When there is a war between countries, it infects the computer of the opponent's country, so that the opponent's computer is not smooth and the information cannot be transmitted in time.

Malicious plug-ins: pop ads to deceive users into leaking information (like QQ small pop-up window prompting winning the lottery).

The above are just a few examples, viruses have a wide range of categories, all of which are designed to achieve a certain purpose, but some are also for fun, writing malicious programs to rectify people, etc.

Some viruses are benign viruses, such as some **malicious**, some are hoaxes or to earn advertising fees, such as letting you pop up windows all the time, turn off one and pop up one or several, etc.

Some are malignant viruses, which can delete your hard disk partitions, delete your files, or let you enter taobao (**) and so on, enter their**, deceive the user's password, or let the user keep swiping the card, etc.

The above are the characteristics of viruses, to put it bluntly, computer viruses are malicious computer programs.

Anti-virus is included in cybersecurity.

Hello landlord. According to the attribute classification of computer viruses, they can be divided into 4 types: 1. Existence**.

Specifically, it is divided into network viruses, file viruses, and bootstrap viruses, 2. Infection channels, specifically resident viruses and non-resident viruses, 3. Destructive ability, specifically harmless, non-dangerous, dangerous, and very dangerous, 4. According to the algorithm, it is divided into companion viruses, worms, parasitic viruses, mysterious viruses and ghost viruses, which are expected to be adopted.

Virology is a biology major. In the discipline setting of China, trouser virology belongs to the second-level discipline microbiology, and microbiology is a subordinate discipline of the first-level discipline biology. Therefore, in the college entrance examination admission, the major most closely related to the virus is biology major.

Introduction to the Virology Major

Virology is an emerging discipline formed through the mutual penetration and integration between virology and molecular biology with viruses as the research object. Specifically, it is a science in which Hu Chunqing studies the structure and function of the viral genome on the basis of fully understanding the general morphology and structural characteristics of the virus, explores the replication and gene expression of the viral genome and its regulatory mechanism, so as to reveal the molecular nature of viral infection and pathogenicity, and provides a theoretical basis and basis for the development of viral genetic engineering vaccines and antiviral drugs, as well as the diagnosis, prevention and development of viral diseases.
