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.
