The model_host.exe process is a legitimate background program associated with recent updates to Norton 360. It runs as a part of Norton’s background engines, but some users have reported the process utilizing high amounts of GPU or battery. [1, 2]

Key Details About model_host.exe

  • Purpose: It operates as a background host for Norton’s machine learning and AI-driven background tasks.
  • Validity: While it originates from NortonLifeLock, sophisticated malware can disguise itself using the same name. To verify it’s legitimate, open the Windows Task Manager, right-click model_host.exe, and select Open File Location. It should be housed in your Norton installation folder (typically C:\Program Files\Norton Security\...). [1]

How to Manage or Troubleshoot the Process

Because it is a native background service, you cannot permanently delete the file without breaking Norton’s functionality. However, you can manage its impact: [1]

  1. Reduce Scan Resource Load: If model_host.exe is consuming too much of your computer’s performance, open your Norton Device Security dashboard and change your scanning preferences to only run when the computer is idle.
  2. Exclude Specific Files: If you believe the process is interfering with another application, use the Norton Exclusions Guide to add the process or specific folders to the scan exclusion list.
  3. Contact Support: If the program causes heating, battery drain, or severe system slowdowns, reach out to Norton Support to update your software version or troubleshoot the active processes.
