Are computer viruses automatically generated in computer systems?

Computer viruses are artificially created, destructive, contagious and latent programs that damage computer information or systems.

It does not exist independently, but is hidden in other executable programs. When a computer is infected with a virus, it may affect the running speed of the machine at first, or crash and damage the system at worst. Therefore, the virus brings great losses to the user. Under normal circumstances, we call this destructive program a computer virus. (Recommended learning: web front-end video tutorial)

Path of transmission

Computer viruses have their own transmission modes and different transmission paths. The main function of the computer itself is its own replication and propagation, which means that computer viruses can spread very easily, and viruses can usually be spread in an environment where data can be exchanged. There are three main types of computer virus transmission methods:

1) Virus transmission through mobile storage devices: U disks, CDs, floppy disks, mobile hard disks, etc. can all be paths for spreading viruses, and because they are often Move and use, so they are more likely to be favored by computer viruses and become carriers of computer viruses;

2) Spread through the Internet: The network methods described here are also different, web pages, emails, QQ, BBS etc. can be ways for computer viruses to spread over the Internet. Especially in recent years, with the development of network technology and the operating frequency of the Internet, the speed of computer viruses is getting faster and faster, and their scope is gradually expanding;

3 ) Spread by exploiting weaknesses in computer systems and application software: In recent years, more and more computer viruses have spread by exploiting deficiencies in application systems and software applications. Therefore, this approach is also classified among the basic modes of computer virus spread.

The main symptoms of a poisoned computer

There are many main symptoms of a poisoned computer. Any computer abnormality may be related to viruses. When a computer is infected with a virus, it is difficult to detect it unless it attacks.

But when a virus attacks, it is easy to feel it from the following symptoms:

Work will be abnormal; inexplicable crash; sudden restart or failure to start; program Unable to run; disk bad clusters increase inexplicably; disk space becomes smaller; system startup slows down; data and programs are lost; abnormal sounds, music or some meaningless screen greetings appear; normal peripherals are used abnormally, For example, there is a printing problem, the characters entered on the keyboard are inconsistent with the screen display, etc.; exceptions require the user to enter a password.
