WM97/Opey-AX is a Word macro virus that will change the Word application user information to include:
UserName = "OPEY A."
UserAddress = "(DCS) PHILIPPINES".
It will also change the File|Properties information to Author = "CARLO O." and Title = "GREAT".
The virus hides the Tools|Macro and Tools|Customize menu options.
On 9 September, 1 January, 1 October or 14 November, the virus will add some lines to C:\autoexec.bat which display the text "HAPPY BIRTHDAY TO YOU !!!" and "from: CARLO O." when the PC boots. The user will then have to press the space bar to continue loading Windows.
