Protect, maintain, and manage your computer with Windows Live OneCare, the always-on PC-care service from Microsoft. Working quietly in the background on your computer, OneCare protects against viruses, spyware, hackers, and other unwanted intruders.
All-in-one Protection and maintenance
In one convenient package, Windows Live OneCare helps protect your computer, uses its optimization features to keep your PC running at its speediest, and even regularly backs up your important files:
-Protection Plus uses antivirus and Antispyware scanners, a managed two-way firewall, and integrated anti-phishing technology to protect your computer from viruses, worms, Trojan Horses, hackers, phishing, and other threats. It runs continuously, but you can scan individual files and folders for viruses on demand simply by right-clicking them. You can even scan attachments you receive via Windows Live Messenger or MSN Messenger.
-Performance Plus regularly defragments your hard disk, removes any unnecessary files that may clog your computer, and helps ensure important security updates from Microsoft are installed efficiently and on time.
-Backup and Restore regularly copies your important files and settings to CD, DVD, external hard disk, network drive, or other data-storage device.
-Instant Help provides online help anytime you need it, 24 hours a day, 7 days a week.
