On my one PC MS Windows Live OneCare crashes upon bootup. On my other computer I can't send/receive email without turning off the firewall even though MS Outlook is set to allow access to the internet. Sure you have free support, but the support is worthless. All they do is blame the problem on other software on your computer even though your computer was working great until you loaded their software. The free products you can find on the internet work better than this software that you have to pay for.
