F-Secure Virus Descriptions : Rut

NAME:	Rut
ALIAS:	DVD

W97M/Rut is a Word 97 macro virus.

VARIANT: Rut.A

When an infected document is opened, W97M/Rut.A infects the global template. After that every document that is saved is infected.

During infection, the virus might cause Visual Basic compile errors. Anyway, the virus will still be able to replicate.

The virus activates its payload in every 10th, 18th and 27th day of the month. At this time it displays a dialog with the following text:

        Created by F?D
        DVD version 1.0

        (C)opyright 1997

This dialog contains two buttons as well. If user selects the "OK" button, no further action is taken. However, if "About" button is selected, the virus asks user to enter a text string which is either

        I LOVE HD-LWP

        DJAJA HD-LWP is Good

depending the number of the seconds. If the string is entered correctly, the virus displays yet another message box with the text:

      Terima kasih telah mengetikkan dengan  benar.
      Saya dedikasikan kreasi saya ini untuk HD- LWP. Semoga HD-LWP
      selalu dilindungi oleh-Nya.  Jangan takut DVD tidak akan merusak data
      Anda, apalagi sampai menghapusnya. DVD hanya akan mejeng setiap
      tanggal-tanggal tertentu saja.  Created by F?D
