Trojaner-Board - kann mir bitte jemand helfen (analyseergebnisse)? danke im voraus...

hallo liebe experten,

ich bin mittlerweile am verzweifeln. habe mir wohl vor 2 tagen einen trojaner eingefangen, der sich vor allem durch folgendes bemerbar macht:

internet-verbindung wird gekappt, nachdem mcaffee eine virusscan-warnung rausgibt:

name:svchost2.exe
ordner: c:\windows
erkannt als: backdoor -cgz
anwendung: iexplore.exe

das ganze passiert bei jedem internet-start.

folgende analysen habe ich laufen lassen...bite sag mir jemand, was ich tun soll, oder ob eine windows-neuinstallation die einzige lösung ist:
