Avast detects t r o j a n in Xcode Previews

I'm completely new to Xcode.
The MacOS executable for Xcode Previews is normally 174K. Using Time Machine I find it has always been so.
Avast removes that executable to it's "Virus Chest".
I restore it from Time Machine to a temp directory and re-run Avast finds it again. I'm not actually *using* Xcode Previews as far as I know, my simple apps (not SwiftUI etc) still compile and run.
(Hmm... title above had "******" where I entered the word "t r o j a n") with no spaces. Fixed it. Can't delete this comment.
Is it a question you could forward to AVAST, to understand what they detect ?
This just happened to me too ... let me/us know if you find out more; I'll do the same
I've pinged Avast "community" with this info. There seems to be no direct support channel, at least not for freeware version users as I am. No response yet, will update as I receive any.
Same here on my side... Not using the Xcode Previews as far as I know... Suddenly Avast alerts that it got infected when I opened my Mac, never before it did so and I was not downloading or updating anything... Strange!
