    Types of Computer Virus
                      There are various types of computer viruses that infect the computer in different ways. The
                      most commonly known categories of computer viruses are:

                      Program File Virus

                      A Program file virus, also known as a file-infecting virus, is a type of computer virus
                      that targets and infects executable files (such as .exe, .com, .sys, etc.). When an infected
                      program file is run, the virus code is also executed, which can then spread to other files,
                      corrupt them, or make them unusable.

                      Boot Sector Virus
                      A Boot sector virus is a type of computer virus that infects the boot sector of storage
                      devices like hard disks, floppy disks, or USB drives. It specifically targets the Master Boot
                      Record (MBR) or the boot sector, which is responsible for loading the operating system
                      during the startup process. Once the system is infected, the virus can spread to other

                      disks that are used with the infected computer. The most commonly known boot sector
                      viruses are Michelangelo and Stoned.

                      Macro Virus
                      A Macro virus is a type of virus that targets and infects documents, particularly files that
                      use macros, such as Microsoft Word or Excel files. When a user opens an infected document,
                      the macro virus is executed, potentially spreading to other documents and affecting the
                      system. The virus may then infect other files by embedding its malicious code into macros

                      within the user's documents. Additionally, some macro viruses do send themselves via
                      email by automatically attaching to messages and sending them to contacts in the user's
                      address book, thus spreading further. Melissa and Bablas are the most commonly known
                      macro viruses.

                      E-mail Virus
                      An E-mail virus is a type of computer virus that transmits from one computer to another
                      through e-mail messages. Some e-mail viruses can also be transmitted as an infected
                      attachment with the e-mail message. The virus can become active when the recipient

                      opens  the  infected  email  attachment  or sometimes  even clicks  on  a  malicious  link.  It
                      sounds very simple but an e-mail virus can erase files, destroy information and cause
                      computer crashes.

                      WORMS

                      A worm is a self-propagating program that works without human intervention. It is a kind
                      of malware that uses a computer network to send copies of itself to another computer on
                      the same network.
