Windows Live OneCare includes antivirus, antispyware, two-way firewall and anti-phishing technology for all your security needs. It regularly defragments and cleans your hard disk drive, and also offers backup and restore functions. Development and test work is complete for the next major release of OneCare and will be available, in store and on the web, at the end of January. Those who have already subscribed will automatically receive the newer version. The new release sports support for Windows Vista while improving XP support, many new language platforms, as well as overall performance improvements - none of which could have been possible without beta testers.
