Mi problema es que a la hora de enceder el ordenador pierdo la conexión a internet, es exactamente a la hora, y el problema se soluciona reiniciando el ordenador (sin desconectar el modem ni nada). Mi compañía es telecable, y les he llamado y me han asegurado que tengo un virus, ya que cuando se me desconecta el internet yo sigo teniengo dirección ip. He pasado el antivirus NOD32 y me detectó 4 virus y los eliminó, después pasé un antitroyano que me bajé, el TrojanHunter, y me dectectó 3 troyanos, pero después de todo esto me sigue pasando el problema. No se mucho de ordenadores, me gustaría que me dijerais que puedo hacer para solucionar este problema.
Gracias de antemano.

Saludos! bueno, vamos a descartar problemas virales. Haz lo sgte:

- Apaga la opcion Restaurar Sistema si tienes Windows ME o XP.
- Entra en Modo Seguro
- Escanea con:


Spybot S&D actualizado
Ad-aware actualizado (FULL SCAN)

- Sin salir del modo seguro, realizas lo sgte en todas las cuentas de usuario:

Pasa el CCleaner.
Limpia el registro con RegSeeker (opcion limpiar registro).

- Inicia en modo normal y escanea con:

Ewido On-Line.
Kaspersky On-Line.

Nos dejas el reporte ke estos antivirus te generen aki.

bueno, he hecho todos los pasos y sigo teniendo el problema.
Otra cosa que puede servirles de ayuda es que desde que me pasa esto, también me pasa que al navegar por el explorer me hace un "extraño" la ventana, apareciendo la parte de arriba de azul en blanco y también la barra de tareas de abajo en blanco en vez de en azul. Esto me sucede durante uno o dos segundos, sólo una vez durante esa hora antes de que se me corte la conexión. No se si tendrá algo que ver o no, pero antes no me pasaba.

Este es el reporte del ewido on-line:

Hola. Proba con la herramienta Winsock XP Fix.

salu2

pero dónde la aplico? en el modo a prueba de fallos?
y con el restaurar sistema apagado?

gracias

Hazlo en modo normal.

salu2

Nada, pasé la herramienta esa y sigo con el problema.

hola soldier45

tengo una duda

-ve a panel de control->Agregar o quitar programas->Verifica si tienes intalado NewDotNet

salu2
Recuerda volver

no, no me aparece en el panel de control el NewDotNet.

He desinstalado el Nod32 viendo que no me detectaba el problema, y he instalado el Kaspersky, he hecho un análisis en My Computer, y me ha detectado dos virus de algo llamado Adware, ya he oido a más gente con un problema con ese virus, no se si será ese el causante del corte de conexión. Este es el reporte del kaspersky:

Hola

Bueno, utiliza la opcion de neutralizar del kaspersky, para deshacerte de los virus ke encontro. Y veo ke tienes el norton. Pues bien vacia su cuarentena. Ademas, recuerda ke no debes tener dos antivirus residentes activos, ya ke te ocasionan problemas.
Nos comentas.
