I bought a used gaming laptop that came with Norton Security installed. I removed the main program using the usual Windows uninstall process, but a "Norton LifeLock" file or folder is still present. Windows says it cannot be deleted because it is being used by another application, even though no other programs or user profiles appear to be open. What is the safest way to remove Norton and its leftover files completely?

The safest approach is to use Norton's official removal tool. Security software often installs services and drivers that a normal uninstall leaves behind, and the dedicated tool is designed to remove those components cleanly. Restart afterward and check Windows Security to confirm Microsoft Defender is active.
A reputable uninstaller such as Revo can scan for leftover files, services, and registry entries after the normal uninstall finishes. Review the items it finds before deleting them rather than removing unrelated files blindly.
Try uninstalling it from Windows Safe Mode if a Norton service is keeping the folder locked. Safe Mode starts fewer third-party processes, so the remaining files may be removable there. Don't manually delete system files unless you're certain they belong to Norton.
If the laptop was already cluttered or you don't know what the previous owner installed, the cleanest option may be to back up your files and reinstall Windows 11 from official installation media. That removes Norton along with any other unknown software, but make sure you have backups and the necessary license or recovery information first.
Revo's free version is usually enough for this. Run the normal uninstall first, then let it scan for remaining Norton-related entries.
