What is a macro virus and how does it spread?
Macro viruses are special macros that self-replicate in the data files of applications such as Microsoft Word and Excel. The majority of macro viruses infect Word document files. When a file containing infected macros is opened, the virus usually copies itself into Word’s global template file (typically NORMAL.DOT). Any document opened or created subsequently will be infected. Macro viruses become part of the document itself, and are transferred with the file via floppy disks, file transfer, and e-mail attachments.
