I bought a used gaming laptop running what I believe is Windows 11, and Norton Security was already installed. I followed instructions to uninstall it without using the official removal utility, but a remaining file or folder labeled "Norton LifeLock" is still present. Windows says it cannot be deleted because it is being used by another application, even though I have no other programs or user profiles open. What is the safest way to remove Norton and its leftover files completely?

If the software refuses to uninstall, try removing it from Windows Safe Mode, where most of its background services will not be running. A clean Windows reinstall from a USB drive is the most thorough option, but it will erase the laptop, so back up personal files first.
A reputable uninstaller such as Revo can remove the normal program and scan for leftover files, folders, and registry entries. Use its default or moderate scan settings and review the results before deleting anything.
The safest option is to use Norton's official removal tool. Security software often installs background services and protected components that a normal uninstall cannot clean up, so manually deleting the remaining files can cause errors. Restart afterward and check that Windows Security is active.
A reinstall is really only necessary if the system is already being reset or the uninstaller fails completely. The official removal utility should usually be enough.
