Internet unheimlich langsam geworden

enaz

In den letztem Tagen is meine Internetverbindung über LAN an meinem PC sehr langsam geworden. Um die Schnelligkeit weiter zu testen hab ich das ganze auch auch meinem Laptop über WLAN gemacht, wo die Geschwindigkeit wesentlich besser ist.

Hab meinen Virenscanner Avira Premium Security Suite schon einmal komplett durchlaufen lassen, doch es wurde nichts gefunden.
Deswegen hoffe ich jetzt auf eure Hilfe, weil ich mich damit überhaupt nicht auskennen, welche Dateien wichtig sind und welche nicht
