Hola, gracias por responder, te cuento;

al realizar los pasos mencionados creo que se soluciono a medias, ya que al pasar nuevamente el Nod32, ya no arroja la infeccion (la que trataba el tema), ahora arroja una nueva infeccion "El archivo C:\System Volume information\_restore{5D46A917-B2E4-402C-BC39-DE2FF8A3379F}\RP72\A0025443.DLL está infectado con aplicación Win32/Toolbar.MyWebSearch."

de todas maneras describo los pasos seguidos, y que me ayudes nuevamente a eliminar este vicho. gracias

1.- Elimine lo que estaba dentro de la carpeta C:\Archivos de programa\ESET\infected

MHZIA0BA.NQF

MHZIA0BA.NQI

2.- Elimine como mencionaste

C:\Archivos de programa\AskTBar\SrchAstt\1.bin\A5SRCHAS.DLL
C:\Documents and Settings\hUgO_rAP\Configuración Local\Temp\NERO14808\Toolbar.exe

3.-Ejecute ATF-Cleaner

4.- Por ultimo, el Report de kaspersky online
