Computer Virus And Antivirus

A computer virus, which is similar to a flu virus, is designed to spread from the host to the host and has the ability to replicate itself. Similarly, in the same way as the flu virus can not reproduce without a host cell, computer viruses can not reproduce and spread without programming any files or documents.

In more technical terms, the computer virus is a type of malicious code or program that is written to change the way a computer is powered up, and it is designed to spread from computer to computer. A virus is executed by executing or applying a valid program or document supporting macros to execute its code. In this process, a virus has the ability to create unexpected or harmful effects, such as corrupting or destroying the data, the system harm the software.

What are the different types of computer viruses?

1. Boot sector virus

A boot sector virus is a type of virus that infects the floppy disk’s boot sector or the master boot record of the hard disk (which infects the boot sector of the hard disk instead of MBR). … While boot sector viruses are infected at a BIOS level, they use dos commands to spread to other floppy disks.

Most file factors only repeat and spread, but some unknowingly harm the host programs. There are also file in factors which overwrite host files. Some files carry infector payloads that are highly destructive, such as hard drive formatting, or benign, display of messages like.

8. Multipartite virus

The multiparty virus is a computer virus that is infected and spread in many ways. This term was previously prepared to describe the virus, which included DOS executable files and PC BIOS boot sector virus codes, where both parts are viral themselves. Prior to the discovery of the first of these, the virus was classified as a file or boot in the factor.

9. Macro virus

A macro virus is a computer virus that is written in the same macro language for software programs, including word processors such as Microsoft Excel or Microsoft Word. When a macro virus infects a software application, it is a sequence of actions to automatically start when the application is opened.
