Hi Josh,
Thanks for reaching out to Microsoft Q&A. I understand your concern regarding the “Software Loopback Interface 1.”
The Loopback interface (127.0.0.1) is a required component of Windows networking and cannot be removed or disabled. It is not an indicator of hacking, and no external traffic can reach your device through the loopback address. Because of this, Windows does not provide any PowerShell or CMD command to remove or block it.
If you believe your device is compromised, please try the following steps:
1, Scan for malware
- Run Windows Security > Virus & threat protection > Quick scan
- Then run Scan options > Full scan
- Optionally run Microsoft Safety Scanner (official tool from Microsoft)
2, Check for unauthorized software
- Go to Settings > Apps > Installed apps
- Uninstall anything unfamiliar
3, Reset network configuration
- Open Command Prompt (Admin)
- Run:
netsh winsock reset
netsh int ip reset
ipconfig /flushdns
4, Create a clean environment
- Backup your data
- Perform Settings > System > Recovery > Reset this PC
- Choose Remove everything for the most secure reset
