Buenas noches,
Aqui os dejo mi log para ver si me podéis quitar el icono del Critical system error. He seguido vuestras guías y parece que el Virusburst esta borrado pero tampoco estoy seguro ya que de vez en cuando, se abre la pagina de virusburst!
Gracias!

Hola, que tal......


Tu log no muestra mucho, al parecer lo conseguiste en el modo a prueba de fallos, los logs debes sacarlos en el modo normal


Descarga las siguientes herramientas:

• DelPSGuard v4.1.6
  
• Killbox
  
• Regseeker
  
• Disk Cleaner

Paso 1:

• Desactiva la restauracion del sistema
  
• Configura el sistema para ver todos los archivos ocultos

Paso 2:

Ejecuta el hijackthis sin tener ningn otro programa abierto, marca y dale FixChecked a las siguientes entradas:

O21 - SSODL: astrogeology - {2be26361-58a2-4836-be57-b838f02fec3f} - C:\WINDOWS\system32\qxfgcg.dll



Paso 3:

• Reinicia el sistema en modo a prueba de fallos (modo seguro)

Copia y pega las siguientes entradas en el Killbox (una a la vez) donde dice "Full Path of File to Delete" y le das click al boton rojo con cruz blanca del programa para eliminar el archivo:

C:\WINDOWS\system32\qxfgcg.dll


Ejecuta la herramienta DelPSGuard.exe


Limpia los temporales y cookies con el Disk Cleaner

Limpia el registro de windows con el Regseeker (pasalo varias veces hasta que no quede nada por limpiar)



Paso 4:

Reincia el sistema en modo normal

Haz un chequeo con los antivirus online Kaspersky y Ewido


Nos comentas como te fue y dejas un nuevo log para ver como quedo



Salu2

Buenas noches,

Ahora parece que ha desaparecido el icono asi como el virus burst. Aun así despues de utilizar Spy Sweeper me sale que tengo trojan-downloader-zlob y pone los siguientes indicios:

HKCR\emediacodek.chl
HKLM\s..\emediacodek.chl
HKLM\s..\safetyalerte2006\

Como puedo borra el trojan? Os mando el log por si véis algo adicional!

Lo que te muestra el spy sweeper son entradas del registro, las mismas no representan en realidad peligro, pero si el spy sweeper no las puede borrar, usa el regseeker para buscar los siguientes nombres (uno a la vez):

emediacodek.chl

safetyalerte2006


Borra cualquier clave que consiga el regseeker con esos nombres


El log de hijackthis está limpio
