1. Explain all the types of computer virus
Answer:
1.File infecting virus
A virus that attached itself to an executable program. It is also called a parasitic virus which typically infects files with .exe or .com extensions. Some file infectors can overwrite host files and others can damage your hard drive’s formatting.
2. Macro Virus
This type of virus is commonly found in programs such as Microsoft Word or Excel. These viruses are usually stored as part of a document and can spread when the files are transmitted to other computers, often through email attachments.
3. Browser Hijacker
This virus targets and alters your browser setting. It is often called a browser redirect virus because it redirects your browser to other malicious websites that you don’t have any intention of visiting. This virus can pose other threats such as changing the default home page of your browser.
4. Web Scripting Virus
A very sneaky virus that targets popular websites. What this virus does is overwrite code on a website and insert links that can install malicious software on your device. Web scripting viruses can steal your cookies and use the information to post on your behalf on the infected website.
5. Boot Sector Virus
These viruses are once common back when computers are booted from floppy disks. Today, these viruses are found distributed in forms of physical media such as external hard drives or USB. If the computer is infected with a boot sector virus, it automatically loads into the memory enabling control of your computer.
6. Polymorphic Virus
This virus has the capability to evade anti-virus programs since it can change codes every time an infected file is performed.
7. Resident Virus
A resident virus stores itself on your computer’s memory which allows it to infect files on your computer. This virus can interfere with your operating system leading to file and program corruption.
8. Multipartite Virus
A type of virus that is very infectious and can easily spread on your computer system. It can infect multiple parts of a system including memory, files, and boot sector which makes it difficult to contain.
