How to tell if a computer virus is type 5

Let me start by telling you how many types of viruses there are.

A computer virus is a command or program that is inserted into a computer to destroy data that affects the use of the computer and cannot replicate itself.

Computer viruses are different from medical viruses, they do not occur naturally, but are exploited by computer hardware or software vulnerabilities or vulnerabilities to compile instructions and programs, and then lurk in the computer medium through a certain way, and when encountering certain conditions, they will be activated, and other programs are copied by themselves or naturally evolved into some programs, so as to achieve the purpose of infecting programs and destroying computing resources.

Characteristics of computer viruses

1. Reproduction.

Like a biological virus, it can reproduce, and when your program is running, it is replicating itself, and whether it is multiplying is an important factor in determining whether it is a virus.

2. Infectious.

The speed at which the virus replicates and then produces variants is so rapid that it is difficult to prevent, and infectivity is the basic characteristic of the virus. Computers will always spread from infected computers to non-infected computers through various accumulations, causing them to not work. Any other computer associated with this computer can also be infected with the virus.

3. Latentity.

The virus is designed to occur at a predetermined time, it will not be detected until the scheduled time, and when the time comes, it will destroy the system, and some can even be carried on the disk for several years, and once the time is ripe to get the opportunity to operate, it will multiply and spread. When the time comes, some will be marked by special symbols, some will directly destroy the system, some will format the disk, and some will directly delete the disk files.

4. Concealment.

Some viruses can remain dormant on the disk for several years without showing themselves, and some can be detected, and it is very difficult to hide them when they appear.

5. Triggerability.

Sometimes the virus must be latent in order to hide itself, but after a long time of incubation, the lethality may be weakened or even gone, so the general virus is hidden when it appears, and then this is the condition that the virus can be triggered as soon as the virus can be triggered during the operation of the computer.

Viruses usually set themselves to start automatically in order to commend the computer when the system boots. What's more, they register themselves as system services, giving priority to other programs to start. The following is a collection of ways to identify computer viruses, welcome to read.

Viruses generally achieve their goals by hiding themselves, so where are viruses generally hidden in the system? Generally speaking, the following three aspects are the general ways in which the virus hides.

Hide yourself through the process: The virus will definitely generate a task to enter the key path, and the virus process will be terminated, then the virus will be terminated, and our computer will not be harmed. Because it is easy to terminate the virus program by judging the process of the age bundle, many viruses protect their processes from being terminated through various methods, usually in the following ways:

Hidden processes, multi-process protection, dll insertion.

Hide yourself with startup items: Viruses often set themselves to start automatically in order to be able to self-start and compromise the computer when the system boots. What's more, they also register themselves as system services, giving priority to other programs to start.

Hide yourself through files: The program file, which is the virus itself, is the base camp of the virus, and if the file is destroyed, the virus will not be able to work. However, viruses generally set their properties to hide, which is not visible through normal methods, and it can also break the system's folder options, making it impossible for users to set them to not hide.
