What do computer viruses usually hide?

Computer viruses are usually hidden in external memory. External memory includes: hard disks, floppy disks, optical discs, removable storage devices including mobile hard disks, USB disks, memory cards, etc.

A computer virus is a set of computer instructions or programs inserted by the compiler into a computer program that can destroy computer functions or data, affect the use of the computer, and can replicate itself. Computer viruses are transmissible, hidden, infectious, latent, excitable, expressive, or destructive.

A computer virus is a program that executes code. Just like biological viruses, they have the characteristics of biological viruses such as self-reproduction, mutual infection, and activation and regeneration. Computer viruses have a unique ability to replicate, and they can spread quickly and often hard**.

They can attach themselves to various types of files, and they spread along with files as they are copied or transferred from one user to another.

Usually hidden in the system folder.

or in the Applications folder.

Computer viruses are programs that are prepared or used in a computer.

"A set of computer instructions or programs that destroy computer functions or destroy data, affect the use of a computer, and can replicate themselves". This entry is an disambiguation entry. There are two types of viruses, this entry is about computer viruses, and for biological viruses, see the other entry "viruses".

Computer virus

It is clearly defined in the Regulations of the People's Republic of China on the Security Protection of Computer Information Systems and refers to "a set of computer instructions or programs inserted by the compiler into a computer program that destroy computer functions or data, affect the use of the computer and can be self-replicated". Unlike "viruses" in medicine, computer viruses are not naturally occurring, but rather a set of instructions compiled by some people to take advantage of the inherent vulnerabilities of computer software and hardware.

or Procedure**. It can lurk in the computer's storage medium (or program) through a certain way, and be activated when a certain condition is reached, and put its own exact copy or possible evolution into other programs by modifying other programs, thereby infecting other programs, destroying computer resources, and causing great harm to infected users.

Main feature: reproduction.

Infectivity. Latent.

Concealment. Destructive.

Computer viruses.

It is a kind of noisy dangerous program or a paragraph hidden on the storage medium in the computer system. A computer virus is a computer program that is prepared by the author.

A set of computer instructions or programs that can affect the use of a computer and can self-replicate a set of computer instructions or programs that can be inserted into the computer to destroy computer functions or data.

Computer viruses have the following characteristics:

Parasitic. Computer viruses are parasitic in other programs, and when the program is executed, the virus plays a destructive role, and Qingbo is not easy to be detected before the program is launched.

Infectivity. Computer viruses are not only destructive in themselves, but also contagious, and once the virus is replicated or varied, it is difficult to prevent it. Contagiousness is an essential characteristic of the virus.

Computer viruses are usually hidden in system folders or application software folders.

"Computer virus" refers to a set of computer instructions or programs that can be self-replicating and self-replicating that are compiled or inserted into computer programs and that destroy computer functions or data.

Latent concealment.

Destructive triggerability.

When it is stored, it can be hidden in the system folder or application folder, and it must be in the memory when it is running.

The answer was B, and I tried them one by one.

Hello 1, different viruses hide and disguise programs are different, so the location is also different.

3. Use Computer Manager - Antivirus - Comprehensive Detection and Killing, you can detect the virus.

4. Because PC Manager has two major cloud antivirus engines and the largest cloud virus database in China, it can judge hidden and disguised viruses according to virus micro-characteristics and intelligent cloud identification.

If you have any other questions and problems, please come to the computer manager business platform again to ask questions, and we will do our best to answer your questions.

Usually the virus program is hidden in the system files, but it depends on the main attack trend and purpose of the virus, some viruses can even penetrate the firewall scanning, the virus is many and diverse, but the most basic purpose is to destroy some files of the system, so as to achieve the final instructions of the virus!
