Trojaner-Board - windows update funktioniert nicht mehr

hallo...
mein windows starter netbook kann seid fast 3 monaten keine updates mehr installieren.....nach zahlreichen virenscannern kontrollen....systemwiederherstellungen....nachdem ich in der config zahlreiche sachen probiert habe und sonst auch google zu dem problem wieder und wieder befragt habe bleibt der "fehlercode 80072efe unbekannter fehler bei windows update" immer noch bestehen.die einzigen sachen die mir bleiben sind mein rechner platt zu machen oder diese möglichkeit mit hijackthis.
wobei ich mich mit diesem programm nicht auskenne und google meinte man solle vorsichtig sein um nicht eventuell etwas falsches zu entfernen.

daher komme ich zu euch....

den logfile habe ich auch....vllt könnt ihr mir aus dieser misere helfen...
