Technical Details


When an infected document is opened or close, W97M/Hubad.A infects the global template. After that the virus infects all documents that are closed or opened. During infection it creates an temporary file, "c:\Hubad.dll".

The virus also hooks the "File/Print" menu. When the active document is printed from an infected system, the virus adds a picture of a woman to the end of the document.

W97M/Hubad.A also removes the "Tools/Macros" menu, and hooks "Tools/Macros/Visual Basic Editor" rendering it unusable.
