Sign-In; Auto-Complete and Registry Error Issues

My computer is running;

  • Window XP Home Edition operating system
  • Internet Explorer 8 browser
  • Norton Internet Security 2012 and  Norton Utilities 15 security software

I’m experiencing the following problems;

  • Windows ID; “keep me signed in“ feature does not always work; frequently requires logging in
  • The “remember me” feature when logging in onto websites does not work after scans
  • The “auto complete” function does not work, even though I have it checked off under options
  • "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ Windows Search\Gather\Windows\System Index Missing or Invalid"  consistently shows up twice after a Norton scan

I haven’t been able to determine if these are Windows or Norton issues; any help would be appreciated.

 

Thanks
