Technical Details



WordMacro/Safwan activates on the 10th of October. At this time it displays a dialog box with this text:

Happy Birthday
        Is it your birthday today?
        Yes  No

If the answer is yes the virus does not infect the opened document.

Otherwise the virus only spreads. The name of the virus comes from a text macro it created to check if it has already infected NORMAL.DOT.

Safwan was reported to be in the wild in summer 1997.
