Onecare includes a firewall, anti-virus, back-up and a system tune-up into one package.
Microsoft have not announced a released date as yet for the product, and it is unclear whether the company plans to charge for the software (note - setup screenshot two might suggest a subscription model is in the works). When Onecare was announced in May, Microsoft received criticism for offering anti-virus software that protected users from failings in the Windows OS. With Longhorn only just entering beta phases, one might draw the conclusion that Microsoft took the decision to offer a product like this to protect users against serious Windows flaws that require serious Windows updates. This aside, the Antivirus business is a lucrative one; with a 'unique' insight into the way its software works, Microsoft could add another integrated product to a already crowded market.Beta testers report the program is surprisingly good.
