Technical Details


This is the polymorphic macro virus. It contains twelve macros in the
module “aljadezz”: FileSaveAs, Mutate, EditFind, AutoOpen, FileSave,
FilePrint, Inserta, ToolsMacro, ViewVBCode, ToolsCustomize, FileTemplates,
Retro.


The virus replicates on executing one of the macros: FileSaveAs, EditFind,
AutoOpen, FileSave, FilePrint. It uses polymorphic routine inserting random
comments into the virus code.


The macro EditFind erases the system files:


C:WINDOWSWIN.COM
C:CONFIG.SYS
C:AUTOEXEC.BAT
C:COMMAND.COM

On printing (FilePrint) the virus adds a page with the text:

-=INFECTADO CON EL ALJADEZZ VIRUS=-

The virus then deletes the files:

C:WINDOWS*.*
C:*.*

The virus also erases the anti-virus programs:
