Trojaner-Board - whAgent.exe / ctfmon.exe -> Viren? Brauche Hilfe!!

Ich habe folgendes Problem:
Spybot entdeckt den Webhancer. Ich kann ihn dann auch löschen, nur beim nächsten Neustart meines PC ist der Webhancer immer noch da. Somit lässt er sich nicht entfernen.

whAgent.exe startet bei jedem Start des Rechners, genauso wie die ctfmon.exe!ich habe gelesen, dass sie die Leistung des Rechners beeinträchtigen!
Ich bitte nun um Hilfe, diese Probleme zu lösen!Wie kann ich das entfernen?
