Hola, soy algo novato en esto de loas antivirus, troyanos y todo lo relacionado.
He estado leyendo y veo que utilizais la herramienta Hijackthis, pues bien, mi ordenador que es nuevo va muy lento y se me ha ocurrido pasar la herramienta y pegaros el log por si vosotros, que lo sabeis itnerpretar, veis algo que pueda ser la causa de esa lentitud.
Muchas gracias de antemano.

Hola joanmv, te doy la bienvenida al Foro de InfoSpyware

Tu log de HijackThis esta limpio y si ya seguiste los "11 Pasos para eliminar Malwares" pasando los AntiSpywares y Antivirus que ahí se mencionan y estos no encontraron nada, tu problema no es por un malware.

Descarga CCleaner v1.4 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).

Una vez que este termine de limpiar todo, actualiza "Java", hace una Desfragmentación del disco con la opción de Windows y pasa por www.windowsupdate.com para descargar todos los parches disponibles (si tu sistema lo permite)

• Descarga y ejecuta la utilidad Advanced WindowsCare, para reparar y optimizar a fondo tu PC.

Reinicia y nos contas los resultados.
