Microsoft makes emergency security fix

Microsoft has released an urgent update to stop hackers taking control of computers with a single email.

The unusual bug, in Microsoft anti-malware software such as Windows Defender, could be exploited without the recipient even opening the message.

Researchers working for Google’s Project Zero cyber-security outfit discovered the flaw at the weekend. The fix has been specially pushed out hours before the software giant’s monthly Tuesday security update.

Hackers could exploit the flaw simply by sending an infected email, instant message or getting the user to click on a web browser link.

Windows 8, 8.1, 10 and Windows Server operating systems are affected by the bug.

Windows users can check that they are running the latest Windows Defender engine version (1.1.13704.0), which should download automatically, to make sure they are not at risk – or hit the update button.
