The Safwan virus consist of one encrypted AutoOpen macro. When the virus infects NORMAL.DOT, it splits to macros named FileOpen and System32.
Depending on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the suspect file, or ask you for a desired action.

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.
