Marker.AD is macro virus that infects Word documents as well as the global template.
Marker.AD uses the means normally used by macro viruses to spread. First of all, it infects the NORMAL.DOT global template. From then on, it will infect every word document that is opened, closed or stored in the affected computer.
In addition, Marker.AD disables certain Word options, depending on the system date.
Marker.AD is very easy to recognize, as it carries out the following actions:
- When the system date is February 15, it deletes the contents of the current document and saves it, which means that all unsaved information will be lost
- When the system date is the 13th of any month, Marker.AD changes the font of the current document to ‘Webdings’ and saves the document, so it will be unreadable.
