Hola

Recuerda pasar por el windowsupdate.com regularmente y mantener tu sistema actualizado.

Bueno, veamos ese reporte.

Recuerda seguir estos pasos para la reparación.

1. Ver los archivos ocultos de tu sistema
2. Desactivar la restauración del sistema
3. Iniciar el sistema en el modo «a prueba de fallos» o «modo seguro»
4. Haz los pasos con todos los programas cerrados salvo el que estés usando para la reparación o limpieza.

Deberás marcar estas líneas en el Hijackthis para reparar:

• O2 - BHO: (no name) - {0000CC75-ACF3-4cac-A0A9-DD3868E06852} - (no file)
• O2 - BHO: MyBHOSpy - {C52CBAEC-D969-4635-9F50-426CC15CE463} - (no file)
• O3 - Toolbar: (no name) - {2CDE1A7D-A478-4291-BF31-E1B4C16F92EB} - (no file)
• O16 - DPF: {0FFFFFFF-0FFF-0FFF-0FFF-0FFFFFFFFFFF} - http://www.pcflashbang.com/statistics/inst.exe

Después de haber hecho esas reparaciones, ejecuta estas otras aplicaciones por si se le ha pasado algo al HijackThis:

• Ad-aware SE
• Disck Cleaner
• Spybot Search and Destroy
• RegSeeker. De este programa deberás usar principalmente la opción de «limpiar el registro»

Tras estos pasos y reparaciones, cuéntanos como evoluciona el tema.

Felicidad

hice lo mencionado y luego de algunas otras cositas, pude resolver el problema, eso creo, por las dudas aqui le envio el log, por si quedo algo sin resolver, pero aun asi, gracias por todo lo que aportaron, gracias de nuevo..
