Trojaner-Board - Trojaner-Verdacht nach gehacktem Steam-Account

Hallo, also wie oben bereits geschrieben wurde gestern mein Steamaccount gehackt. Ich habe mich inzwischen an Steam gewand und die Sache ist vorerst vom Tisch, ich kannmich also wieder ohne Probleme einloggen.
Als ich das ganze bemerkt habe, habe ich sofort einige Passwörter geändert auf diversen wichtigen Internetseiten. Im Nachinein habe ich aber Angst, das ich ein Trojanisches Pferd drauf habe und die Änderungen sozusagen mitgeschnitten wurden.
Ich habe inzwischen 2 mal Search&Destroy drüberlaufen lassen, 1 mal AdAware und 2 mal AntiVir. Desweiteren habe ich mein Hijackthis LogFile auf hijackthis.de auswerten lassen. Dort waren, wie auch bei den Scannern keine besonderen Vorkommnisse zu erkennen, sprich es hab keine gefundenen Schädlinge. Einzig AntiVir gab mir 5 Treffer aus:
- Trojanische Pferd TR/Agent.31232.M
- TR/Dropper.Gen
- BDS/Hupigon.153170
- TR/Dldr.Delphi.Gen
- DR/AccessDiver.4103.1
Die Daten wurden jeweils in Quarantäneverzeichnis verschoben.
Desweiteren läuft mein System völlig unauffällig was die Auslastung angeht.
Zur Sicherheit wollte ich aber nochmal einen Mensch drüber schauen lassen:
