More Information

W32/Melo-A is a worm for the Windows platform.

When first run W32/Melo-A copies itself to:

C:\WINDOWS\system32\drivers\etc\jesse.exe

and creates the file C:\Confesional.txt. This file can be safely deleted.

The following registry entry is created to run jesse.exe on startup:

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
a
C:\WINDOWS\system32\drivers\etc\jesse.exe

W32/Melo-A deletes all writeable, non-hidden, non-system files in the top folder of the A: and C: drives, replacing them with copies of itself whose filename is <original filename>.EXE.

Registry entries are created under:

HKCU\Software\VB and VBA Program Settings\ok\jessy\

The worm displays the following fake error message box:

Caption:

Message:
No se pueden abrir archivos debido a la falta de un componente
