Hallo Leute,
ich habe seit gestern 19:10 Uhr das Problem, dass, obwohl Kontakt mit dem Router besteht Firefox und auch IE keine Internetverbindung aufmachen können. Das Zurückspielen einer älteren Windows 7 Sicherung brachte auch nur Abhilfe für 10 Minuten.
OS ist Windows 7 prof 64 bit.
Ich habe die Maschine mit avast!, Malewarebytes gescannt. Keine Auffälligkeiten.
Das Ergebnis von HijackThis habe ich mal gepostet. Vielleicht kann sich das mal jemand anschauen. Vielen Dank im Voraus.
Gruß Jürgen

Platform: Windows 7 SP1 (WinNT 6.00.3505)

Macht das SP1 Probleme? Kann ja nur heute oder gestern installiert worden sein.

Hallo Cosinus,
nein. Das SP1 habe ich heute "drübergenagelt". Komischerweise läuft jetzt alles.
Gruß
