Types of Computer Viruses
A computer virus is a program that is designed to damage your computer, programs, and files. Like a virus in a living thing, a computer virus can spread if it is not removed. Some viruses are more dangerous than others. One of the most common places for a computer virus to appear is on a file found on the Internet or attached to an E-mail. For example, you may have a virus that just pops a message box on your screen, and then the virus is disabled, or you can have a virus that deletes half of your hard drive. Computer viruses didn't really exist until the mid 1980s. The first computer viruses were created in university labs to demonstrate how much of a threat the vicious code could be. There are many kind of viruses that exist today. Some of the most common of Computer Viruses are: File Viruses, Boot Sector/Partition Viruses, Multi-Partite Viruses, Trojan Horses, File Overwriters, Polymorphic viruses, and Stealth Viruses.

Multi-Partite Viruses are the worse of both file and boot sector viruses. They can infect the host software components. These viruses spread like a file virus, but still insert itself into a boot sector or partition table. Because of this, they are difficult to remove. An example of this type of virus is the Tequila virus. A97M: Access Macro viruses that replicate in Access 97. HLLC: High Level Language Companion virus. These are usually DOS viruses that create an additional file to spread.
