Mac: External Device detected EFI Recovery Preboot
« on: April 24, 2021, 02:42:48 PM »
Since installing Avast Security, I have always received the following messages about connected drives either immediately after starting the computer or during operation. Unfortunately, I can't find anything on the Internet about what that means and whether the connected drives (I haven't connected anything externally) pose a security risk?

See screenshots in the attachment.

Earlier antivirus scanners did not report anything like this.



seit der Installation von Avast Security erhalte ich immer entweder direkt nach dem Computerstart oder während des Betriebs folgende Meldungen über angeschlossene Laufwerke. Leider finde ich nichts im Internet darüber, was das zu bedeuten hat und ob die angeschlossenen Laufwerke (ich habe extern nichts angeschlossen) ein Sicherheitsrisiko darstellen?

Siehe Screenshots im Anhang.

Frühere Antiviren-Scanner haben sowas nicht gemeldet.

this is the first time I am hearing about such behaviour. Please can you send us support package ( mentioning your user name, ideally followed by a mail to ondrej.kolacek at mentioning that you have done so (so I do not miss it accidentally)? I will try to check what could be the reason based on that information.
Kind regards,
