Macro virus

A macro is a series of commands and actions that helps automating some tasks - usually a quite short and simple program.A macro virus can be spread through e-mail attachments, removable media, networks and the Internet, and is notoriously difficult to detect.These malicious macros may start automatically when a document is opened or closed, without the user's knowledge.However, this is uncommon as it is usually not fruitful for the virus coder since the installed software is usually noticed and uninstalled by the user.[6] Current versions of Microsoft Office block macros by default in files originating from the internet, a change that first appeared in April 2022.
