W97M/Turn is a Word 97 class infector.
When an infected document is opened, the virus infects the global template. After this has been done, it infects every document that is closed.
It replaces the "Tools\Macros\Visual Basic Editor" menu with a message box:
The Visual Basic environment could not be initialized. Please run setup to install it correctly.
