Looks like there is a big flaw in Internet Explorer. Excerpt from this link:

MILLIONS of computers across the globe are threatened by a virus that could open them up to criminals, allowing access to personal details.

A major security flaw has been discovered in Microsoft’s Internet Explorer web browser, which is used by 70 per cent of all computers, the Daily Mail reports.

There are fears that cyber criminals will exploit the flaw to steal passwords, access internet bank accounts, or send out spam e-mails.

Some two million computers are believed to have fallen victim after visiting apparently safe websites, but the contagion threatens to sweep the world wide web.
