Muchas grácias ElPiedra, creo que se ha acabado el problema, te comento.
He pasado SUPERAntispyware y me ha detectado un troyano en una carpeta llamada system volumen information la cual debe estar oculta en C porqué no la tengo localizada, el ejecutable se llama A0003022.EXE, el cual lo tengo en cuarentena, supongo que lo tendré que eliminar, correcto?.
Luego he pasado el CCleaner como has indicado y después el Combo fix. Luego he navegado durante una hora y media y no me ha aparecido ninguna ventana emergente cosa rara ya que, antes, en solo dos minutos tenia como cuatro ventanas emergentes. A ver si ahora las hecharé en falta!!! YO creo que podemos decir PROBLEMA SOLUCIONADO. Te adjunto el reporte de Combofix:
