This is a Microsoft Excel macro virus. Sofa spreads to Excel spreadsheets once it has copied its virus code to the default startup directory. It does this by creating a file called \MSOFFICE\EXCEL\STARTUP\BOOK.XLT

Sofa contains these macros: Auto_Open, Auto_Range, Current_Open, and Auto_Close.

Sofa activates by checking the title bar text of Excel to read

Microsofa Excel
 

Otherwise, the virus just spreads.

Sofa was found in the wild in USA in December 1996.
