The service's main new feature is the OneCare Circle, which links PCs together over a wireless connection to make them manageable from a single place. OneCare Circle allows, for example, a parent to see that a child has disabled the firewall on his or her PC and to turn it back on. It also helps centralize data backup by allowing a hard drive connected to any linked machine to serve the whole home network.
The service also includes the new Start Time Optimizer, which helps users load only the programs they require at startup, thus accelerating the startup process. In addition, it includes a "Proactive Fixes and Recommendations" feature to help optimize PC performance, and it helps maintain wireless networking security.
That's all great. However, the main purpose of this program is to protect against malware. As we know from prior AV comparatives, OneCare doesn't do that too well. Will this version fare better? Wait for a comparative before considering buying it.
