OK mein problem ist folgendes: ich hab eine datei von einem freund geschickt bekommen und natürlich gestartet :/ nichts passierte. also frag ich mich ob ich mit bifrost infiziert wurde, weil er das schon bei anderen gemacht hat.
hoffe btw das ich das jetzt richtig gepostet hab ich hab vor kurzem meinen pc formatiert und nachdem ich das wichtigste draufhatte den virus angenommen - falls es einer war
mein HJT:

Hi,

coole Sache. Also Du kennt da einen, von dem Du weißt, dass er seinen Bekanntenkreis mit Bifrost infiziert, bekommst von dem eine Datei geschickt und machst einen Doppelklick drauf. Den Menschen nennt Du auch noch einen Freund. Hörst Du es im Hintergrund? Da lachen meine Goldhamster. Ups, ich glaub einer ist gerade geplatzt.

Bei Bifrost-Verdacht ist ein HijackThis wertlos, ganz normal dass der sich dadrin nicht blicken lässt. Der hier sagt schon mehr aus:

Lade SilentRunners von dieser Seite auf den Desktop runter. Alle Programme schließen und SilentRunners starten. In der Abfrage "nein" wählen, damit die "supplementary searches" ebenfalls ausgeführt werden. Die weitere Abfrage mit "ja" bestätigen. Nun warten, bis SilentRunners mit einem Fenster bestätigt fertig zu sein, dies kann einige Zeit dauern. Das Logfile findest Du danach auf dem Desktop. Dessen Inhalt posten.

Karl

zum glück gleich an den richtigen geraten ^^
danke im vorraus und

Hmm, sieht unverdächtig aus. Hast Du diese Datei noch? Wenn ja, dann mal bei VirusTotal hochladen und scannen lassen, die Ergebnisse bitte vollständig hierher kopieren.
