Microsoft has released an emergency update for its Internet Explorer browser to fix a bug that cyber-thieves are known to be exploiting.
The software and services giant warned the bug could let attackers hijack a web browser and use their access to install malware. Hackers are believed to have built booby-trapped webpages harbouring malicious code that infects visitors.
Microsoft said versions of Internet Explorer nine to 11 were vulnerable but anyone regularly using Internet Explorer is being urged to download and apply the patch.
Just over 8 percent of PC users are still relying on Internet Explorer although use of the browser has declined.
