Google has said that starting March 1, some of its web applications such as Google Docs will not work "properly" with Microsoft's Internet Explorer 6, as it begins phasing out support for the browser identified as the weak link in a cyber attack on the search engine, BBC news has reported. The internet giant has recommended that individuals and firms should upgrade "as soon as possible." Earlier this month, hackers used a flaw in Microsoft's Internet Explorer (IE) browser to target the Gmail accounts of Chinese human rights activists.
