Windows 7: Windows 7: Windows Update Code 80072EFD & Windows Firewall Fehlercode

Hallo,
Heute komme ich nach Hause, schalte meinen Rechner ein und bemerke, dass irgendwas nicht stimmt.
In der Systemsteuerung finde ich eine deaktivierte Firewall vor will ich diese einschalten, so bekomme ich den Fehlercode 0x80070474, die Windows updates funktionieren auch nicht, es kommt nur der Fehlermeldungscode 80072EFD.
Außerdem ist mir aufgefallen, dass mein PC nicht vernünftig nach außen durch einige Programmme kommuniziert. Die programme finden keine Internetverbindung.

Das habe ich bisher versucht:
Probleme erkennen und behben - ohne erfolg
Vollständigen Virenscann mit antivir - kein Fund (neben bei eines der Programme, die nicht nach außen kommunizieren wollen; keine Updates möglich)
Systemwiederherstellung- schlägt fehl
MicrosoftFixit- selber Fehlercode wie bei den Windowsupdates

Hier nochmal HijackThis Logs, vielleicht könnt ihe ja was damit anfangen:
