Trojaner-Board - Freigelassener Trojaner TR/dldr.exchanger.baz nun endgültig von PC gelöscht?

Hallo liebe Forenmitglieder,

ich habe ein Problem mit einem Trojaner namens TR/dldr.exchanger.baz . Mein Antivir hat ihn schon des Öfteren rechtzeitig erkannt und ich habe die betroffene Anwendung dann nie ausgeführt, sondern gelöscht.
Nun war er aber in einer Anwendung versteckt, die ich ausgeführt habe, während sie noch verpackt war. Danach erst habe ich sie entpackt, und Avira meldete sich prompt mit dem Trojaner-Fund. Ich habe ihn in die Quarantäne verschoben. Nun habe ich ihn aber schon "freigelassen", und weiß nicht was er schon angerichtet hat. Beim Avira-Suchlauf wurde er gleich zweimal wieder entdeckt. Aber hat er sich mittlerweile schon irgendwo eingenistet und ausgebreitet? Wie kann ich das feststellen?
Ich habe Hijackthis laufen lassen, konnte mit der Online-Analyse nicht viel anfangen. Es wollte auch erst nicht starten. "For some reason your system denied access to the Hosts file.[...]" Ich klickte auf Ok und es lief doch. Die logfile füge ich unten an. Auch FastScan und Trojan Remover habe ich laufen lassen, ein "Fund" namens BTTray.exe, unter dem sich Trojaner laut Google gerne mal verstecken. Ich glaube ich habe die Datei aus dem Autorun entfernen lassen. Aber ich verstehe offensichtlich nicht viel davon! Mich wundern auch die ganzen "file missing" Einträge (siehe unten). Ich habe übrgens Windows 7.
