What are the different types of computer viruses?

There are following different types of viruses:

• Web scripting virus
• Browser hijacker
• Resident virus
• Direct action virus
• Polymorphic virus
• File infector virus
• Multipartite virus

1. Boot sector virus

This type of virus can take control when you start — or boot — your computer. One way it can spread is by plugging an infected USB drive into your computer.

2. Web scripting virus

This type of virus exploits the code of web browsers and web pages. If you access such a web page, the virus can infect your computer.

3. Browser hijacker

This type of virus “hijacks” certain web browser functions, and you may be automatically directed to an unintended website.

4. Resident virus

This is a general term for any virus that inserts itself in a computer system’s memory. A resident virus can execute anytime when an operating system loads.

5. Direct action virus

This type of virus comes into action when you execute a file containing a virus. Otherwise, it remains dormant.

6. Polymorphic virus

A polymorphic virus changes its code each time an infected file is executed. It does this to evade antivirus programs.

7. File infector virus

This common virus inserts malicious code into executable files — files used to perform certain functions or operations on a system.

8. Multipartite virus

This kind of virus infects and spreads in multiple ways. It can infect both program files and system sectors.

9. Macro virus

Macro viruses are written in the same macro language used for software applications. Such viruses spread when you open an infected document, often through email attachments.
