Buenos dias. Les comento mi problema: Mi pagina de inicio de IE es reemplazada constantemente por about:blank - "quick web search" y aparecen repetidamente pops. Cuando navego mas de 5 minutos en Internet, Paint y el Notepad se activan solos. En el panel de control aparecen dos programas "search wizard" y shopping wizard" que no se dejan desinstalar y que me envian a una pagina web que promociona un tal Spyfigther.

Luego de correr Norton antivirus, Ad-Aware SE, Spybot y Microsoft Antispyware, el problema sigue igual . Asi que encontre su interesante pagina web y descargue hijackthis. Los resultados son:

Hola te doy la bienvenida al foro, no te olvides de pasar por WindowsUpdate periódicamente para tener actualizado el sistema, desinstala desde el Panel de Contro el SpyFighter ya que es un falso antispyware, luego sigue estos pasos:

1.- Descarga las herramientas AboutBuster y CWSHredder de aquí y 023Fix, y descomprímelas en el escritorio de Windows pero no las ejecutes aun.

2.- Apaga el "Restaurar Sistema"

3.- Activa la opción Ver Archivos Ocultos

4.- Reinicia en Modo a Prueba de Fallos

5.- Cierra todos los programas, ejecuta HijackThis y dale "Fix Cheked" a estas entradas:

De preferencia imprime las indicaciones para que se te haga mas facil seguirlas.

Hola
Realicé el procedimiento que me sugirieron, pero el problema ahora es que el internet explorer abre pero dice que no tengo conexión a red, (para escribir esto me tocó usar el computador de un amigo) en general ninguna aplicacion que requiera de la red funciona.

Aca les envio el resultado del Logfile of HijackThis, a ver si me ayudan a saber que fue lo que paso, y solucionar este problemilla

Mil gracias

¿Utilizas Proxy? ya que estas entradas al parecer así lo indican:

R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Int ernet Settings,ProxyServer = kgb.emn.fr:3128

R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Int ernet Settings,ProxyOverride = local.,emn,*.mde.emn.fr

Si seguiste lois pasos al pie de la letra no debe haberse presentado inconvenientes.

Descarga y ejecuta la herramienta WinsockFix para reparar la conexión y nos cuentas como te fue.

Saludos

Corri el winsockfix pero no logre reestablecer mi conexion a internet. Luego revise los datos del proxi y encontre que los numeros IP habian desaparecido. No se si el proceso para acabar con el spyware los habra borrado. Luego de reintroducirlos, mi conexion a internet volvio a funcionar y el IE marcha perfecto. Ya no aparece la pagina about:blank y el molesto homesearch desaparecio.

Mil gracias por su ayuda.
