What is norton360.exe?

norton360.exe is the core component of Norton 360, the antivirus and security suite. It runs in the background to perform real-time scanning, threat detection, firewall enforcement, and update checks, often spawning child workers for parallel tasks during scans.

This executable loads the Norton security engine, coordinates real-time protection, signatures updates, and cloud threat intelligence, and delegates work to helper components. It runs with minimal UI while the main Norton UI remains responsive.

Quick Fact: Norton 360 uses a multi-layer protection model, with the engine actively monitoring files, processes, and network activity for rapid threat detection.

Types of Norton Processes

Is norton360.exe Safe?

Yes, norton360.exe is safe when it's the legitimate file from NortonLifeLock downloaded from official sources (norton.com or pre-installed by manufacturer).

Is norton360.exe a Virus or Malware?

The real norton360.exe is NOT a virus. However, malware sometimes disguises itself with similar names to trick users.

How to Tell if norton360.exe is Legitimate or Malware

  1. File Location: Must be in C:\Program Files\Norton LifeLock\Norton 360\Engine\norton360.exe or C:\Program Files\Norton\Norton 360\Engine\norton360.exe. Any norton360.exe elsewhere is suspicious.
  2. Digital Signature: Right-click the file in File Explorer → Open file location → Right-click norton360.exe → Properties → Digital Signatures. Should show "NortonLifeLock, Inc.".
  3. Resource Usage: Normal usage is 1-15% CPU per process, 100-300 MB total memory. Extremely high usage when protection is idle is suspicious.
  4. Behavior: Norton 360 should only run when protection is enabled. Multiple instances when protection is off indicates tampering.

Red Flags: If norton360.exe is located in unusual folders (like Temp, AppData, or System32), runs when protection is disabled, has no digital signature, or uses excessive resources constantly, run a full system scan with Norton and a second antivirus. Be wary of similarly named files.
