I’ve scanned it prior to unzipping with Avast, as well after, found nothing. There is no installation because it’s portable version, Avast only reacted when I ran Audacious.exe.
I guess gdbus.exe can be some unsigned driver or something like that. As I said, uploading it to Virus Total, didn’t find anything, even Avast said “undetected”
