This Anti-Beacon immunizer blocks access to a few dozen Internet servers that are contacted by Windows to submit telemetry data
So it's possible Windows Defender is showing Settings Modifier:Win32/PossibleHostsFileHijack due to antibeacon adding entries to the hosts file to block telemetry. Perhaps Windows Defender does that due to it being possible that malware might add entries to the hosts file to block it's servers as well as legitimate programs like anti-beacon and other programs that block telemetry.
