Macro.Word97.Day
Description Macro.Word97.Day
This is a silly but very dangerous macro virus. On opening an infected document the virus copies its body into the global macros area (NORMAL.DOT). Other documents get infection on their opening.
When any document is being opened, the virus checks the system date, and starting from 2nd June 1999 writes into the AUTOEXEC.BAT file a set of commands that delete all data on C: and D: drives.
The virus body contains the comment:
it is a good day to die
