Trojaner-Board - Keine zulässige Win32-Anwendung Malware?

Hallo, lese seit einem halben Jahr hier den ein oder anderen Logfile mit. Habe nun selbst Probleme bezüglich Malware/Trojaner/Virus bekommen. Und mein Logfile sieht mMn auch nicht ganz sauber aus, würde aber gerne von euch Experten mehr darüber wissen. Danke im Vorraus!
Ich habe neulich bei einer exe Datei (welche bei meinen Freunden funktioniert) folgende Fehlermeldung bekommen:
... ist keine zulässige Win32-Anwendung. UAC deaktivieren etc. hat mir auch nicht weitergeholfen.
Hier mein Hijackthis-Log.

Laut Malwarebytes ist nun alles gereinigt, die Datei kann ich jedoch immer noch nicht öffnen.
