I am using Norton utility for the first time, and getting a warning on five or six different items, which are described as High Priority Highlighted Value is Missing or invalid I wonder if someone could advise me if these are important enought to need attention. The Norton Utility asks me if I want to reapir them, and when I say yes I am told they are repaired. Yet the next day or whenever I run the check again they re-appear HKEY_CLASSES_ROOT\Bxpfile\Shell\open\command HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoom\MUI Cache HKEY_CURRENT_USER\Software\Netscape Navigator\User Trusted External Applications HKEY_CURRENT_USER\Software\Netscape\Netscape Navigator\Viewers HKEY_CURRENT_USER\Software\SupportSoft\ProviderList\talktalk\users\Owner\Job Cache HKEY_CURRENT_USER\Norton\Nu_15_help/ I am totally inexperienced, and quite old so any help would be much appreciated.
