Microsoft's Live OneCare security software has failed tests which check how well it spots and stops malicious programs designed to attack Windows. OneCare was <A HREF="http://news.bbc.co.uk/1/hi/technology/6418965.stm">the only failure among 17 antivirus programs</A> tested by the AV Comparatives organization.
Microsoft's software only spotted 82.4% of the 500,000 viruses that the independent group subjected it to. The test is the second in less than a month that Microsoft's anti-virus software has failed.
