In this issue, the editor will bring you about the two categories of computer viruses. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

There are two types of computer viruses: file-based viruses and system-guided viruses. The file virus mainly infects the executable file (.exe) and command file (.com) in the computer; the system boot virus refers to the computer virus parasitic in the disk boot area or the main boot area.

There are two types of computer viruses: file viruses and system-guided viruses.

File type virus

File virus is a kind of computer virus, mainly by infecting executable files (.exe) and command files (.com) in the computer. A file-type virus modifies the source file of the computer to make it a new file with virus. Once the computer runs the file, it will be infected, thus achieving the purpose of transmission.

There are two types of file viruses: one is to add the virus to the front of the COM, and the other is to add the virus to the end of the file.

File-based viruses are mainly transmitted to .com and .exe files.

System-guided virus

A bootstrap virus refers to a computer virus parasitic in the disk boot area or the main boot area.

This kind of virus makes use of the disadvantage of not judging whether the content of the main boot area is correct or not when the system is booted, and invades the system, resides in memory, monitors the system operation, standby infection and destruction in the process of the guided system.

According to the parasitic position of the boot virus on the hard disk, the main boot recording virus and the partition boot recording virus can be subdivided.

The master boot records the main boot area where the virus infects the hard disk, such as cannabis virus, 2708 virus, torch virus, etc., and the partition boot records the active partition boot records of the hard disk infected by the virus, such as globular virus, Girl virus, etc.

The above is the two categories of computer viruses that Xiaobian shares for you. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
