Now a Google search shows MANY people reporting this and probably due to
Windows Defender, yet not one solution?? Win XP had a small Event Clean-up
file to fix Hive problems, such as this. Any bright spark here got any
ideas. Before I get told to go back to XP or Open Source, I LOVE Vista and
its challenges
