This is the OneCare by subscription user forum, the Safety Scanner (different application) has it's own message boards, located here:

On that forum you should mention what internet connection speed you have, if it ever completes your download, what OS you're running, if it ever ran correctly on your system, and if you're getting any error messages returned. It works fine for me, but I'm on XP with a high bandwidth connection.
