A security flaw in all versions of Microsoft's Internet Explorer leaves users wide open for attack, with millions of computers already infected. Microsoft did not say when a patch might be available. Simply opening a Web page in IE can infect an unprotected computer. Proper security protection, not a browser switch, is the best defense.The exploit doesn't require users to click on links or download software from the Internet. Rather, it infects users when they open a Web page. The goal is to steal passwords, according to security experts, gain access to financial data and otherwise steal the victim's identity.
