Macro.Word97.Titasic

Description Macro.Word97.Titasic

This is a quite complex macro-virus consisting of about 400 lines of code, and it contains about twenty macros and functions in one module "astia". It replicates upon document opening. It also creates the infected templates SNRML.SRC and SNRML.DOT in the Word startup directory.
The virus under different conditions displays several messages and manifests itself in several ways. For instance, upon the opening of the macro-diting Word menus, the virus displays MessageBox with Yes/No buttons:
Titasic
Maaf..
Anda jangan coba-coba mengedit, merubah, ataupun menghapus makro Titasic..!!
Anda hanya bisa merekam makro, menyimpan, menggunakan
serta menghapus makro buatan Anda
Apakah Anda ingin merekam makro..?

On "Yes", the virus inserts the string "'Macro non-Titasic'" into the current document.
Within 45 minutes following activation, it also manifests itself with a video effect.
Titasic.b (a.k.a. W97M.Astia.y and W97M.BMH)
This virus is very similar to the original one. The virus module has the "BmH" name, and upon opening the macro-editing Word menus, the virus displays a MessageBox with Yes/No buttons:
MacroBasic
Are you sure want to create a new macro?

On "Yes", the virus inserts the string "'MacroWordBasic'" into the current document.
In 15 minutes after activation, it also manifests itself with a video effect.
Titasic.e
Upon opening an infected document, this virus infects the global macros area (Normal template). Then it activates a timer that summons the main infection routine every seven minutes. This routine in an opened document deletes all macros, and then copies the virus macros from the global macros area.
The virus blocks Visual Basic Editor from opening by requesting a password, which is "azizoke".
Upon exiting Word, the virus checks the system time. If it is Friday or Sunday and earlier than 9:00 p.m., the virus displays following message:
Ucapan Terimakasih
Terimakasih buat dosenku yang amat sangat "bijaksana",
yang telah memberiku nilai JELEK. Saya merasa bangga
dan sungguh-sungguh bangga terhadap dosenku itu.
Sekali lagi saya ucapkan terimakasih!.
Semoga mereka tetap di STIKI.
buat teman-teman, ma'af mengganggu.

BadBoy.1000.c

Description BadBoy.1000.c

This is a harmless memory resident parasitic encrypted virus. It hooks INT 21h and writes itself at the beginning of COM files are executed. This virus uses System File Table on infection. It is divided on 9 blocks of code and data (installation block, data block, INT 21h block e.t.c.). When the virus installs itself into the memory, 8 of these 9 blocks can be rearranged in any order depending on the system timer. On infection the virus saves encrypted image of its TSR copy into the file, so orders of code blocks in two infected file can be different.
