To remove Norton Antivirus from a PC, using the Norton uninstaller is recommended as the first step. If this fails, booting into a Linux live CD to delete Norton files is an alternative. Users have noted that simply deleting files is insufficient due to associated drivers and registry entries, which can lead to further issues if not handled correctly. Some have successfully removed Norton by slaving the drive to another computer and manually deleting system and registry files, although this method is not advisable due to potential complications. It's also highlighted that contacting Norton support may not yield timely assistance, especially if the software was acquired second-hand without installation resources.
