Trojaner-Board - "Free Virusscan" bring Explorer zum Absturz

Hallo, seit gestern bekomme ich jedesmal wenn ich versuche auf einen Ordner zuzugreifen folgende Meldung:

Egal wie ich das wegklicke, ich werde dann immer auf eine Website gebracht die versucht meinen PC zu scannen (hxxp://free-virusscan.com) und der Explorer stürzt ab.
Ich vermute mal, dass ich mir was mit einer Software eingefangen habe, die ich über *husttorrenthust* geladen habe. HJT hat jedenfalls folgendes ergeben:
