Fund von Application.AppInstall (A) kritisch?
 
Hallo liebe Freunde,

ich bin gerade dabei einen die letzten 3 Jahre nicht genutzten Win7 Rechner auf Win10 upzugraden. Allerdings will ich natürlich vorher meine Daten sichern. Damit ich meine externe Festplatte nicht verseuche, scanne ich mein System immer vorher mit Emisoft Emergency Kit (EEK) und danach mit ESET Online Scanner vor dem Backup.

Es wurde folgendes gefunden:

Mir ist klar, dass für Windows 7 keine Reinigungen mehr vorgenommen werden, was auch richtig ist. Die Ergebnisse scheinen alle auf die damalige Verwendung von Avira Antivirus und dessen Browsertoolbar zurückführbar zu sein. Ich bin mir bei diesen Einträgen vom EEK allerdings nicht sicher:
Code:

C:\ProgramData\apn        detected: Application.AppInstall (A) [224108]
C:\Windows\TEMP\APN-Stub        detected: Application.Win32.WebToolbar (A) [224131]

Da ich das System eh platt machen werde, ist meine Frage hauptsächlich, ob ich meine Dateien einfach sichern kann, oder ob ich damit meine externe Festplatte und damit andere Rechner in Gefahr bringe.

Ich danke schonmal vielmals!

Da wurde doch nur irgendein Müll und Junkware gefunden.
Einfach nur persönliche Dateien sichern und fertig. Programme, Spiele und deren Setups zu sichern macht eh keinen Sinn.

Worufuwuddo 15.04.2020 15:46

Das ist genau das. Es handelt sich nur um ein paar Bilder, Videos und Spielstände. Wenn ich das bedenkenlos sichern kann, bin ich schon glücklich.

stefanbecker 15.04.2020 16:12

Kannst du. Und was wichtig ist: Nach der Installation von Windows 10 keinen Virenscanner installieren. Windows 10 hat den Defender an Bord, der ist völlig ausreichend.

Worufuwuddo 15.04.2020 17:04

Danke Stefan, genau das werde ich auch tun. Avira ist nur ein Relikt aus vergangenen Tagen...
