Marker.BN is a macro virus that infects Word global template (NORMAL.DOT file) and all the documents generated with it. By doing so, it will infect all the documents that the user opens, closes, saves, etc.
In addition, Marker.BN uses stealth techniques, such as disabling the dialog box that prompts the user to enable or disable the macros that the document contains. By doing so, Marker.BN prevents the user from disabling the macros used by the virus to carry out its infections.
Marker.BN activates between June and December, 2000 or later and can use up the hard disk space, as it makes 999,999,991 copies in the Windows directory of the Word documents that the user closes.
Marker.BN is a polymorphic virus, as it modifies its content every time it carries out an infection.
Marker.BN is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.
However, a clear indication that Marker.BN has infected those documents containing macros, is that the warning messages that allow Word documents to be opened without enabling their macros, are disabled.
