Hola. Desde un tiempo. Tengo el problema que el ordenador se ha ralentizado bastante.
Cuando busco algo en Google y cuando pincho en los resultados, automáticamente se me redirecciona a otra página que no deseo.
Me aparecen ventanas sobre programas anti espías diciendo que tengo el ordenador infectado.
He utilizado algunos anti espías que recomendáis aquí. Y se han borrado muchos spyware. Pero este problema persiste.
Aquí tenéis mi log a ver si veis algo.

Hola JorgedG, te doy la bienvenida al Foro de InfoSpyware.

El log de HijackThis esta limpio, por lo que segui estos pasos:

Descarga CCleaner y ejecútalo usando primero su opción de "Limpiador" para borrar cookies, temporales de Internet y todos los archivos que este te muestre como obsoletos, y luego usa su opción de "Registro" para limpiar todo el registro de Windows (haciendo copia de seguridad).

Descarga, actualiza y ejecuta

• SUPERAntiSpyware
• FixWareOut

• Descarga la herramienta ComboFix.exe y guárdala tu escritorio.
• Hace doble-click en el archivo combofix.exe y seguí los avisos.
• Cuando termine este generara un reporte que tendrías que pegar en este mismo mensaje.
  • Nota* Puede que algunos Antivirus como Panda detecten un falso positivo en ComboFix pero no hay que preocuparse por esto.

Reinicia y nos contas los resultados.

Salu2
