Virus.MSWord.Bismark1 or Bismark1, or sometimes called Bismark, is a pretty destructive Macro virus for Microsoft Word.

Behavior

The virus contains 7 macros:

  • AutoOpen
  • BisMark
  • ToolsMacro
  • ToolsCustomize
  • ViewVBcode
  • FileSave
  • FileClose

The virus infects upon the opening or saving of documents (AutoOpen, FileClose). Upon opening a file, the virus turns off the VirusProtection options.

Payload

Upon saving a document, the virus erases files belonging to well known anti-viruses:

c:\program files\norton antivirus\Virscan2.dat
c:\vdoc\*.*
c:\f-prot\*.*
c:\program files\antiviral toolkit pro\*.*

Upon entering the menu item Tools/Macro, the virus installs the password "Bismark" on the document, and outputs the Balloon:

Word Macro Virus BisMark1
You Should Have Left Me Alone, I Was Not Hurting Anything. Now I'am Mad!

After this, the virus shuts down Windows. On Friday at 12:00, the virus inserts the autocorrect entries "the" on value "Word Macro Virus BisMark1, Written By Talon".
