A macro virus is
Macro viruses are the most prevalent and successful type of virus. These viruses attach themselves to application documents, such as word processing files and spreadsheets, and use the application's macro programming language to execute and propagate. Macro viruses use the macro programming capabilities that many popular software packages, such as Microsoft Office, use to automate complex or repetitive tasks.
These viruses tend to spread quickly because users frequently share documents from applications with macro capabilities. In addition, when a macro virus infection occurs, the virus infects the template that the program uses to create and open files. Once a template is infected, every document that is created or opened with that template is also infected. The Concept, Marker, and Melissa viruses are well-known examples of macro viruses.
