Technical Details



Variant:Model.A

When an infected document is opened, the virus infects the global template and disables the built-in macro virus protection.

After that all documents opened or created will be infected.


Variant:Model.B

This variant is functionally identical with W97M/Model.A, except the macro virus protection is not disabled.


Variant:Model.E

W97M/Model.E contains a payload that activates when the active document has been edited for four hours. At this time it will minimize and maximize every document window in Word.

This variant also infects random documents from the current directory.
