This is a typical example of a false positive on a false positive that isn't. Avast blocks because just too much of the real code is shown to make the alert work and final effect the blocking. A human being would never have made such a mistake. So yes in your case a false positive/not a false positive as Avast detection experiences or detects it. You could ask Avast Team for an exclusion for such detections coming from the bleeping computer malware removal URL. We cannot as we are just volunteers with relevant knowledge. Exclusions for detection definitions can only be made by Avast Team Members, and we here are not.
Have a nice day,
