Microsofa
Type:
Macro

The XM.Sofa virus is the first member of the second family of Excel macro viruses. First discovered by SARC in early December of 1996 (west coast USA), XM.Sofa, like other Excel macro viruses, is written in MS Visual Basic and it spreads by copying its own viral macros to other MS Excel spreadsheet hosts. Unlike XM.Laroux (the first known, viable Excel macro virus) which infects by creating a file called PERSONAL.XLS in the default startup directory, XM.Sofa spreads by way of a file called BOOK.XLT placed in the alternate startup directory.
