Brief Description 

    

Buendía.A is a macro virus that, on the eleventh of each month, displays the text Hoy es un buen día[user_name], where [user_name] is the name of the infected user.

As the majority of macro viruses, Buendía.A:

  • Infects files with a DOC extension  and the Word template.
  • It prevents the Word macros and the Visual Basic Editor that are incorporated in the application from being used.

Buendía.A reaches computers in an infected Word 97 document, with a DOC extension. It then infects the Word template(NORMAL.DOT file) and spreads its infection to all the Word documents generated with this template.

Visible Symptoms 

    

On the eleventh of every month, Buendía.A shows the following text on screen:

Hoy es un buen día [user_name].

The text [user_name] corresponds to the name of the user assigned the infected computer.

A minute later, Buendía.A shows the text Realmente hoy es un buen día.

Then, Buendía.A prevents access to the Visual Basic Editor incorporated in Word. This means that the menu option Tools - Macro - Visual Basic Editor will not work. Neither can this option be accessed using the key combination Alt+F11.

If the editor is accessed, Buendía.A shows the following warning No pudo encontrar o iniciar Microsoft Visual Basic.

If the macros are accessed, Buendía.A displays the message No pudo encontrar o iniciar Visor de macros.
