I have another antivirus or firewall program. Can I also install Windows Live OneCare?
No. Before installing Windows Live OneCare, make sure to uninstall any other antivirus or firewall programs currently on your computer. OneCare might not run, or it might slow the performance of your computer, if you install it when other antivirus or firewall programs are also installed on your computer. During setup, OneCare checks for common antivirus and firewall programs that are known to conflict and provides means for you to uninstall them.

I previously downloaded the beta version of Windows Live OneCare, but did not purchase it. Does the beta version still work?
Existing beta users will still be able to use the OneCare service with the latest updates and virus definitions for several months, but you will eventually need to transfer to the paid subscription service in order to maintain the service updates.

Why does Windows Live OneCare require me to have a Windows Live ID?
As a subscription service, OneCare needs a way to identify you and allow you to access information contained in your account. OneCare uses your Windows Live ID for this purpose. You can also use your Windows Live ID as your sign-in for other Windows Live services.

How is Windows Live OneCare different from Windows Live OneCare safety scanner?
Windows Live OneCare is subscription-based software that, once installed on your PC, runs continuously in the background and automatically updates itself. Windows Live OneCare offers persistent, always-on security features that generally don’t require any action on your part.

Windows Live OneCare safety scanner is a free Web-based service that gives you quick, on-demand PC health and security scans to help you diagnose and solve problems, but it does not proactively protect your PC against new virus infections.
