Different Types of Computer Viruses


Computer viruses come in many shapes and sizes

Types of Computer Viruses

There are several types of computer viruses that can pose a threat to your identity or the data on your computer. It is a good idea to know about these security threats and how they work. Anti-virus software is highly recommended or everyone who uses computers on a regular basis to protect their personal, financial and most sensitive data.

Browser Hijacker

One type of virus is called a browser hijacker. This works in a way that it takes over parts of the internet browser you are using and redirects it to certain sites. Its purpose is to increase advertisement revenue by bringing traffic to certain web pages. A well-known example of one is called CoolWebSearch. Keep an updated, good antivirus program to help stop these.  Also, be careful in downloading any coupon and shopping add-ons, and programs.  They are often bundled with those.

Directory Virus

A second type of virus is known as a Directory Virus and are also called File System Virus or Cluster Virus. This virus works by changing the path that indicates the files location by infecting the directory of your computer. These infect the entire directory but are usually found in a location in the disk. An example is Dir-2 virus.  These make it difficult to locate your files and may seem that files have disappeared.


Trojan or Trojan horse is sent to your computer by a program that it is hidden inside . A trojan disguises itself to make one believe it is an important or useful program. These are often in highly desirable downloads like games, free software, and even movies or music.  Trojans are different that other viruses, because they don’t multiply or spread.  However, they are very dangerous because they can capture your login information on sites that you input your information.  Trojans are a top tool of cyber thieves who steal your financial and personal data for profit.

Memory Resident Virus

Memory Resident Virus are put on your computers memory. When the operating system runs the virus gets activated and every file that was opened gets infected. Even after execution of the malicious code the virus stays hidden in the RAM. This virus corrupts programs and files that are used in any way. Randex, Meve and MrKlunky are some, just to name a few.

Overwrite Virus

Another type is Overwrite Virus. This virus takes a file and infects it and the information in it is deleted, once that happens the file is partially useless or totally. The file size is not changed even though the content has been replaced. The file needs to be deleted, and you will lose the content originally in it.
