According to the Microsoft website, a macro is a series of commands that you can use to automate a repeated task and can be run when you must perform the task. The use of macro instructions was originally initiated for assembly language programming to perform two main purposes: to reduce the amount of coding that had to be written by generating several assembly language statements from one macro instruction, and to enforce program writing standards.
Nowadays, macros are used for a wide variety of purposes and industries; Microsoft applications currently use Visual Basic for Applications (VBA) programming language to build their macros, and they allow you to choose whether you want to enable or disable existing macros from use. However, when Microsoft was first designing macro features for the Microsoft Office suite, they weren’t thinking about potential internet security risks.
