Borra todas las cookies y el registro con CCleaner:

Vete a Panel de Control--> Java y elimina todos los archivos temporales. (Si utilizas JAVA)

Borrar archivos temporales--> Desde Inicio, Ejecutar, escribe %TEMP%, pulsa Enter y elimina todo el contenido.

Pasale el AVg antispyware. (Actualizalo, y al acabar el Scaneo elije la opcion eliminar, despues guarda el report y lo pegas)
