The exact ship date of OneCare 2.0 is unclear, with one online retailer saying it will be offered early next week and others saying it will arrive earlier. Amazon has already begun accepting orders for OneCare 2.0, which it says will ship next Thursday.
Microsoft has been beta testing OneCare 2.0 since July, billing it as a better way for users to manage their home computing environments and as "a foundation to better address the needs of small businesses," according to a company blog posting.
The software, which can be run on up to three PCs, has new tools for backing up, monitoring and managing home networks. It also has new features to speed up the performance of systems that use the software. Its suggested retail price is US$49.95, but Amazon is offering it for $42.99. OneCare is sold on a subscription basis, so these prices would cover a one-year subscription.
Since it was introduced last year, OneCare hasn't exactly been a runaway hit.
Just last week the software came under fire for changing users' automatic update settings without proper notification, and earlier this year the software ranked last in a test of 15 antivirus products by AV-Comparatives, an Austrian antivirus testing project.
Between September 2006 and September this year, Microsoft has bettered its malware detection rate by about 20 points, Gullotto said. Now, Microsoft's detection rate is usually between 91 percent to 95 percent, depending on the testing plan, he said.
