Windows OneCare Live: Coming soon to beta: "Are you tired of spending time trying to protect and maintain your computer? Are you worried that you're still not doing everything you should to keep it safe and running at optimal performance? If your answer is 'Yes,' then Windows OneCare? is for you. Windows OneCare is built specifically for people who don't have the time or technical expertise necessary to secure and manage a computer on a daily basis. It is a comprehensive PC health service that goes beyond security to take an integrated approach to help protect and care for your computer."
Hmm -- scant details thus far, but if it costs less than Norton Anti-virus and works at least as well, and if the backup etc. features work well, I'm sure many PC users will sign up.
