    • According to the definition, a computer virus is a program designed to change the way a computer operates and is programmed in such a way that it spreads from one computer to another by itself to carry out spiteful actions. A virus is a human-made program used by someone who has malicious intent to access private information, corrupt data, to display humorous messages on the user's screen. The majority of viruses are targeted on computers run on Microsoft windows.
    • If a virus manages to get into the computer or any other device it can cause a lot of damage. It can damage billions of dollars every year if inserted into some computer which is used for highly important data. Viruses can cause damage in several other ways also. To counter the virus many anti-virus programs have been made.

    What are the types of computer viruses?

    There are many types of computer viruses and all of them affect the computer in different ways. Computer viruses keep evolving with technology and take various new forms. Some common types of computer viruses are:

    1. File Virus:

    File virus is also known as a parasitic virus because it damages every file but then keeps the host intact. It typically affects files with .com or .exe extensions. The execution of this virus is not even noticed. It basically changes the start of the program so that the control falls to its code.

    2. Boot sector virus:

    It infects the boot system of the computer. This type of virus executes every time the system reloads or is booted. They are also known as memory viruses as they do not affect the file system. Nowadays, these types of viruses are distributed in the form of physical media such as hard drives or USB.

    3. Macro Virus:

    This type of virus is mostly found on documents such as word and ms excel. Unlike all other viruses, this virus is written in a low language (like C or assembly language). This type of virus usually spreads when a file is transferred from one document to another.

    4. Multipartite Virus:

    This type of virus infects multiple parts of a system including the boot sector, memory, and files. It is infectious and can spread easily on a computer. It is not easy to contain and detect.

    5. Resident Virus:

    This type of virus stores itself on a computer and infects files and other documents. This virus causes program corruption and interferes with the operating system.

    6. Armored Virus:

    This form of a virus is coded and makes it difficult for antivirus software to detect and contain them. It has a variety of techniques to fool the antivirus program like it lies about its real location or uses methods to complicate its code.
