Hallo,
hab seit 2 Tagen das Problem, das mein Antivir nicht mehr unten rehcts in der Taskleiste erscheint. Laut Task Manager läuft es aber. Da ich mal einen Virus hatte der so anfing wüsste ich gerne ob ich mir wieder sorgen machen muss oder einfach Antivir neuinstallieren sollte. Hier das Hjack Log.
Für alle Antworten schonmal ein Dankeschön :-)

Ist unauffällig. Bevor wir da weiter Energie reinstecken, schau erstmal nach ob eine Neuinstallation von AntiVir das kosmetische Problem behebt.

Ok, hbas heute neuinstalliert und das Icon ist wieder da.
Danke fürs drüberschauen :-)

Nur nochmal um sicherzugehen: H.exe ist HijackThis bei dir, wurde umbenannt?

Ja genau. Hab mal gesagt bekommen man soll die .exe unter anderen Namen abspeicher.

Dann ist alles ok
