Computer Viruses

 What are Computer Viruses?

Computer viruses are malicious software programs designed to replicate themselves and spread to other computers. They can be used to damage or gain access to data, steal information, or cause harm to the system. Viruses are often spread via email attachments or downloads, and can cause serious problems if not detected and removed.

Types Of Computer Virus

1. Boot Sector Virus: This virus is capable of infecting the boot sector of a hard drive. It can spread when a computer is booted from an infected disk or flash drive.

2. File Infector Virus: This type of virus infects executable files, such as .exe files. It can spread from one computer to another as a file is shared.

3. Macro Virus: This type of virus is written in a scripting language, such as Visual Basic for Applications (VBA). It can spread rapidly through documents and programs, including Microsoft Word and Excel.

4. Multipartite Virus: This type of virus can infect both the boot sector and executable files. It can spread through email attachments, removable storage devices, and network shares.

5. Stealth Virus: This type of virus uses techniques to hide itself from antivirus programs. It can spread through email attachments and removable storage devices.

6. Polymorphic Virus: This type of virus can change its code to evade detection. It can spread through email attachments and removable storage devices.

7. Worms: Worms are self-replicating programs that can spread quickly across a network without any human intervention. They can spread through email attachments.
