Is norton-sync.exe a Virus or Malware?
The real norton-sync.exe is NOT a virus. Malware may spoof names; verify with the steps below.
How to Tell if norton-sync.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\NortonLifeLock\Norton Sync\norton-sync.exe or C:\Program Files (x86)\NortonLifeLock\Norton Sync\norton-sync.exe. Any norton-sync.exe elsewhere is suspicious.
