Explanation:
A macro virus is a virus that is written in a macro language: a programming language which is embedded inside
a software application (e.g., word processors and spreadsheet applications). Some applications, such as
Microsoft Office, allow macro programs to be embedded in documents such that the macros are run
automatically when the document is opened, and this provides a distinct mechanism by which malicious
computer instructions can spread.
