Descarga el programa HijackThis HijackThis 2.0.2
y colócalo en una carpeta propia para el HijackThis (por ejemplo una carpeta C:\HijackThis\). Ejecútalo y presiona el botón "Do a system scan and save a logfile"; el programa realizará el escaneo e inmediatamente generará el Log, sólo te pedira el nombre del archivo y su ubicación, puedes simplemente guardarlo así como está. Se abrirá el Bloc de Notas, copia todo el contenido y pégalo como respuesta a este tema.
Una vez descargado, da doble click en el icono del HijackThis.exe.
Primero da click en el botón "Config", y aparecerán 7 opciones . Fíjate que no estén tildadas la primera ( “Mark everything found for fixing alter scan”) y la última (“Run Hijack This scan at startup and show it ítems are fond”).Luego presiona "Back"
Para empezar el escaneo de posibles hijackers, clickea en el botón "Scan". Se te presentará una lista con todos los elementos encontrados por el programa .
Baja el HijackThis de aquí:
http://www.trucoswindows.net/descargar-hij...s-2.0.2-87.html
Deberás registrarte en la web para bajar el Hijackthis ya que tiene un registro distinto al del foro.
Salu2
