I've used Norton and McAfee in the past. I am now using a beta product from Microsoft called OneCare. It's by far the best I've used. Works with the firewall - is an antivirus as well as a spyware checker. Once every 2 weeks (I have set that up) is checks for files that need backup - checks my hard drives (defrag, etc.). This happens at 2:00AM. It also alerts you if there might be a problem. I highly recommed it. As it is in beta there is no charge but I do believe there will be a subscription once it's released.
