The early macro viruses were annoying but mostly harmless. Recent ones however, are more destructive. They can delete files or even reformat hard disks. Word macro viruses can work on any platform, which runs word. This means more machines are available for infection.
People exchange documents like they do executables or floppy disks.
It is also quite easy to create or modify macro viruses. Therefore micro viruses are, a real problem and is rather likely that the macro will become more relevant type of virus in the future. An environment which allows macro viruses to spread means, that the general security of one s information is surely and directly at risk. There is however, no need for panic. Yet there is definitely a need for control to be in one s hands.
