If you have ever tried to uninstall a Symantec (now part of Broadcom) security product—such as Norton, Symantec Endpoint Protection (SEP), or Symantec Cloud Secure Web Gateway—you know it is rarely as simple as clicking "Uninstall" in the Windows Control Panel. Stubborn drivers, leftover registry keys, and protected file fragments often remain, blocking future antivirus installations or causing system conflicts.
