I dont know “most” but it’ll certainly be more secure. Per Google, its redesigning the underlying security architecture of OS so users don’t have to deal with viruses, malware, security updates.
But there’s another side to this story. The Chrome OS will be far more Web-centric than Windows, which means that many–if not most–of its applications will be running over the Internet. What’s more, people’s data will be stored “in the cloud,” much of it on servers run by Google. So while Google may help reduce Microsoft’s potential as a single point of failure, it increases its own. If hackers were successful in launching an attack on Google, that would affect not only people’s ability to use Google apps, but the integrity of their data.
