Hallo zusammen

Ich habe ein Problem mit dem Windows Defender.

Etwa alle 20 Minuten kommt vom Windows Defender folgende Meldung:
windows defender has finished downloading the update.
please click OK to finish the updating process.

Danach meldet sich die Benutzerkontensteuerung mit folgenden worten:
Möchten sie zulassen, dass durch das folgende Programm Änderungen an diesem Computer vorgenommen werden.
Programmname: Windows Hostprozess (rundll32)
Herausgeber: Microsoft Windows

Wenn ich dann auf OK klicke passiert nichts. Zumindest nichts sichtbares.

Ich bin mir jetzt nicht sicher, ob ich irgendetwas falsch eingestellt habe oder ob ich mir was böses eingefangen habe.

Awira AntiVir Personal ist installiert (zeigte bei der letzten Prüfung nichts verdächtiges an)
Windows Firewall ist aktiviert
Windows Defender ist aktiviert (Die erwähnte Meldung erscheint auch wenn er deaktiviert ist)

Betriebssysthem: Windows 7 Home Premium 32-bit

1. CCleaner habe ich laut Anleitung des Forums ausgeführt.

2. Malwarebytes habe ich auch laut Anleitung ausgeführt.

Weis wirklich niemand woran das liegen könnte?

Tut mir leid, dass ich so drängle aber ich bin schon ganz verzweifelt.
