This virus has two destructive payloads. The first activates if Word is started at the exact minute - then it attepts to delete the following files: All Excel worksheets ("*.XLS") from Excel directory, All Access databases ("*.MDB") from Access directory, all program groups ("*.GRP") from Windows directory and all help files from the current directory.
The second payload activates if the document is closed when the seconds from the current time is less than eleven. At this point the virus will search for ten different numbers and replace them with other random numbers.
