Characteristics

Files

The worm drops the following files:

%Sysdir%\winini.vbs
%Sysdir%\snd44.gif
%Sysdir%\user44.ico
%Sysdir%\VbScr.xml

And it copies itself as:

%Sysdir%\www.MacDonald.com-index.htm
%UserProfile%\Local Settings\Temporary Internet Files\www.MacDonald.com-index.htm
%UserProfile%\Local Settings\Application Data\Microsoft\CD Burning\www.MacDonald.com-index.htm
%UserProfile%\Favorites\www.MacDonald.com-index.htm
%UserProfile%\Local Settings\History\www.MacDonald.com-index.htm
%UserProfile%\My Documents\My Music\www.MacDonald.com-index.htm
%UserProfile%\My Documents\My Pictures\www.MacDonald.com-index.htm
%UserProfile%\My Documents\www.MacDonald.com-index.htm
%UserProfile%\Start Menu\Programs\www.MacDonald.com-index.htm
%UserProfile%\Start Menu\www.MacDonald.com-index.htm

And it also may copy itself at one of the following locations:

%UserProfile%\Desktop\e-mail from#Sarah_icqGroup@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#imen_nannou@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#ahlem_3ishk@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#amina_kissme@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#amel_sousse@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#sana_hammamet@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#molka_nabeul@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#noura_sfax@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#amani_staracademy@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#sandra_algerie@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#madiha_ariana@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#sonia_malhat_manar2@yahoo.fr.htm

Moreover, if the worm is executed more than 8 times, it will copy itself 99 times under:
%UserProfile%Desktop\message_sandwich{random number}.htm

It creates a copy of itself in the root of all fixed, removable and network drives it finds (except A:\), using the filename www.MacDonald.com-index.htm.

It may copy itself as {filename}.{ext}.vbs if there are some files with one of the following extensions in the sub-folders of the drives:
*.mp3
*.mpg
*.doc
*.xls
*.jpg
(The decision is made randomly).

It infects all .htm and .html files found in the sub-folders of the fixed, removable and network drives.

Registry

  • The worm modifies the following registry entry to count the number of executions of the script:

HKEY_LOCAL_MACHINE\"shell" = "{counter}"

  • It creates the following registry entries to force the execution of the worm at startup or when Internet Explorer is executed:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Main\"Start Page" = "%Sysdir%\www.MacDonald.com-index.htm"

Symptoms

  • The presence of the above files and registry entries.
  • Increase in file size for .html and .htm files
  • The following notification may appear in the systray:

  • The startpage is changed and the following webpage appears when Internet Explorer is opened:


Method of Infection

The virus may arrive on the compromised computer through an infected .html page.

Removal

AVERT recommends to always use latest DATs and engine. This threat will be cleaned if you have this combination.

All Information

Overview -

This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.

Characteristics

Files

The worm drops the following files:

%Sysdir%\winini.vbs
%Sysdir%\snd44.gif
%Sysdir%\user44.ico
%Sysdir%\VbScr.xml

And it copies itself as:

%Sysdir%\www.MacDonald.com-index.htm
%UserProfile%\Local Settings\Temporary Internet Files\www.MacDonald.com-index.htm
%UserProfile%\Local Settings\Application Data\Microsoft\CD Burning\www.MacDonald.com-index.htm

%UserProfile%\My Documents\www.MacDonald.com-index.htm
%UserProfile%\Start Menu\Programs\www.MacDonald.com-index.htm
%UserProfile%\Start Menu\www.MacDonald.com-index.htm

And it also may copy itself at one of the following locations:

%UserProfile%\Desktop\e-mail from#Sarah_icqGroup@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#imen_nannou@yahoo.fr.htm
%UserProfile%\Desktop\e-mail from#ahlem_3ishk@yahoo.fr.htm

Moreover, if the worm is executed more than 8 times, it will copy itself 99 times under:
%UserProfile%Desktop\message_sandwich{random number}.htm

It creates a copy of itself in the root of all fixed, removable and network drives it finds (except A:\), using the filename www.MacDonald.com-index.htm.

It may copy itself as {filename}.{ext}.vbs if there are some files with one of the following extensions in the sub-folders of the drives:
*.mp3
*.mpg
*.doc
*.xls
*.jpg
(The decision is made randomly).

It infects all .htm and .html files found in the sub-folders of the fixed, removable and network drives.
