Als sich aufeinmal in einem Ordner auf dem Desktop viele Symbole auf mysteriöse Weise verändert haben, hab ich etwas Panik geschoben und bin jetzt auf nem Kammerjäger trip.
Was sagt ihr zu diesem Logfile? Ich selbst kann da nichts gefährliches erkennen.

hi,

So funktioniert es:
Posten in CODE-Tags
Die Logfiles anzuhängen oder sogar vorher in ein ZIP, RAR, 7Z-Archive zu packen erschwert mir massiv die Arbeit, es sei denn natürlich die Datei wäre ansonsten zu gross für das Forum. Um die Logfiles in eine CODE-Box zu stellen gehe so vor:

• Markiere das gesamte Logfile (geht meist mit STRG+A) und kopiere es in die Zwischenablage mit STRG+C.
• Klicke im Editor auf das #-Symbol. Es erscheinen zwei Klammerausdrücke [CODE] [/CODE].
• Setze den Curser zwischen die CODE-Tags und drücke STRG+V.
• Klicke auf Erweitert/Vorschau, um so prüfen, ob du es richtig gemacht hast. Wenn alles stimmt ... auf Antworten.

Bitte lade dir die passende Version von Farbar's Recovery Scan Tool auf deinen Desktop: FRST 32-Bit | FRST 64-Bit
(Wenn du nicht sicher bist: Lade beide Versionen oder unter Start > Computer (Rechtsklick) > Eigenschaften nachschauen)

• Starte jetzt FRST.
• Ändere ungefragt keine der Checkboxen und klicke auf Untersuchen.
• Die Logdateien werden nun erstellt und befinden sich danach auf deinem Desktop.
• Poste mir die FRST.txt und nach dem ersten Scan auch die Addition.txt in deinem Thread (#-Symbol im Eingabefenster der Webseite anklicken)
