According to data from the NDP Group, OneCare has had little success in stealing users from the traditional consumer security powerhouses like Symantec and McAfee. While OneCare accounted for nearly 11% of U.S. consumer security suite sales in June, the first full month after version 1.0 debuted, by October its slice had shrunk to 6%. Symantec, meanwhile, remained the dominant player, with 74% of the market in October, while McAfee held down second place with approximately 10%.

OneCare 1.5 will be available from the Microsoft Web site as well as in the retail channel. After a free 90-day trial using the downloaded version, users must pay the $49.95 annual fee. Existing paid users will be able to upgrade to 1.5 free of charge.
