Internet funktioniert nicht

moin leute,
ich hab seit einiger Zeit das Problem, dass sich manchmal browser nicht öffen, also im taskmanager hab ich geschaut und dann ging das bis ein paar Mbits hoch und frohr dann ein und war dann weg. Nun lassen sich die Browser zwar meistens öffnen, aber dafür ist das Internet sehr langsam.
Ich habe mal mit Hijackthis einen Scan gemacht und wollte fragen, ob jemand von euch mir dazu was sagen kann und mir helfen kann?

Sowas nennt man Befall mit Schadsoftware. Und die scheint sich bereits richtig tief ins System integriert zu haben.

 

Das hört sich nicht gut an :/.
Was empfiehlst du mir zu tun?

 

Komplette Neuinstallation oder ein sauberes Image zurückspielen.

 

Also wichtigen Daten externe Festplatte ziehen und dann Windows neu installieren. Was meinst du mit "sauberes image zurückspulen"?
