Windows threat alert triggered by new muse hub preview: wacapew c!

I’m trying out the new hub preview, and the scanner notification thing popped up and said that it was concerned about something with a name along the lines of “wacapew c!”. It appeared to be part of the installer. Any idea what this is? I’ve removed it already…
Edit: perhaps it was simply a script that the scanner uses that I’m referring to? Hmm…
