+7Da die Angriffe von unterschiedlichen IP-Adressen kommen, ist es wohl eine DDoS-Attacke. Da sie über mehr als 24 Stunden andauert, hast Du entweder:
1) Eine statische IP-Adresse
2) Einen dynamischen DNS-Namen
oder
3) Einen Trojaner, der Deine sich verändernde IP-Adresse immer wieder preisgibt.
Falls Du UPnP nicht benötigst, abdrehen.
Um festzustellen, ob es Lücken in der Firewall gibt:
http://www.heise.de/security/dienste/portscan/test/go.shtml?scanart=1
Zur Überprüfung von Punkt 3, falls keine statischeIP:
DynDNS, wenn eingerichtet, abdrehen, UPnP abdrehen, alle PCs, Handys etc vom Netz trennen, Router neu starten, mit einem PC, der sicher frei von Malware ist ins Netz verbinden und feststellen, ob die Angriffe noch kommen.
Vielleicht gibt es noch weitere Tipps von anderen usern, ansonsten: Hilfe durch Profis, was natürlich kostet.
Nachtrag: Falls Du online-Spieler bist: Es gibt auch Gegner, die durchaus in der Lage sind, Dich mit solchen Attacken "einzubremsen".
