Thanks David R! Anyway Avast has "now cleared its reputation in our database based on the findings and removed the detection" in reply to my False Positive submission.
The weird thing is that when I do go back to Capcut to download, it downloads the file directly and no longer goes through that sub-directory of faceulv.com.
So we I don't know if that faceluv was indeed malicious and it's fixed now, or if there indeed was a false positive by Avast earlier.
Regardless, the issue is resolved now.
