Microsoft has released a patch to address critical security flaws in Internet Explorer.
A remote-code exploit in Internet Explorer was used by hackers in China to target Google and between 20 and 30 other large businesses.
This patch is rated 'critical' and Microsoft advised users who do not have automatic-updates enabled to visit the Windows update website and "apply the update immediately".
The security hole in the Microsoft browser allows remote access by hackers if the user visits an infected or malicious website. Microsoft said this attack could be more dangerous to users operating under 'administrator' rights.
Versions 5 - 8 of Internet Explorer are vulnerable to this exploit and the patch will address the issue in these releases.
