ntoskRnl.exe und autoclk.exe als schädlich angezeigt!

#1 Mein Anti-Viren-Programm AVG meldet die Datei C:\Windows\System32\ntoskRnl.exe als "changed", jedoch ohne weitere Angabe von Warnungen oder Gründen. Ein Virusscan über Jotti ergab anschließend, dass ArcaVir darin Heur.W32 aufgespürt hat. Die anderen Programme fanden jedoch nichts, ebensowenig Spybot Search & Destroy und Virustotal.com.

Hier folgend meine Hijackthis-Log File, über die ich auf die als schädlich gemeldete C:\Windows\autoclk.exe gestoßen bin. Virustotal und Jotti melden über autoclk.exe in der Zeile ClamAV: Trojan.Klacc-1. Jotti zusätzlich in der Zeile ArcaVir: Trojan.Klacc.B

Sonst läuft der PC relativ fehlerfrei, nur in letzter Zeit habe ich den Eindruck, dass er beim Hochfahren öfter einfriert. Dann geht gar nichts mehr, nur noch An- Aus-Taste.

#3 Habe die beiden Dateien als Anhang an die o. g. Adresse versandt. Hoffe auf ein baldiges und aufschlussreiches Ergebnis.

Vielen Dank im Voraus.

#4 Sobald die Dateien da sind... Hast du das Archiv mit einem Passwort versehen? Sonst kann es sein, das die Datei von deinem Mailprovider geblockt wird.

#5 Ich habe es mal hierüber versucht, hoffe es klappt.

#6 Die ntoskrnl.exe, die du geschickt hast, ist das Orginal. Bei der anderen Datei denke ich eher an einen Fehlalar von CLAMAV auch wenn der Dateiname schon verdaechtig ist. Du kannst den Hijackthis Eintrag mit Hijackthis fixen.
Ich hab die Datei an Clamav geschickt. Mal schauen, ob sie sich dazu melden, bzw die Erkennung entfernen...
