Un saludo antes que todo.

Desde hace algunos dias tengo problemas con la gorrosa pagina de Inicio"About Blank", asi tambien, con la aparicion de pequeñas pantallas de errores, lo que ha alentado, mi ya de por si lenta computadora.

He corrido ya algunos Antispyware, aunque sin mucho exito, por lo que
de antemano agradezco su ayuda para resolver mi problema.

Anexo el Log.

Y todas las entradas que he marcado en negrita en tu log.

3 - Localiza y elimina (usa KillBox si es necesario):

C:\WINDOWS\TEMP\se.dll
C:\WINDOWS\SYSTEM\BNNP.DLL
C:\Recycled\Q330995.exe

4 - Luego limpia el registro con un programa como RegSeeker por ejemplo.

5 - Reinicia en "Modo a prueba de fallos" o "Modo seguro" y escanea el equipo con Ad-Aware SE y Spybot Search&Destroy.

6 - Usa el Disk Cleaner para limpiar cookies y temporales.

7 - Reinicia y nos cuentas los resultados.

**NOTA: Actualiza el sistema operativo y el navegador.

Saludos.
