If you still use Microsoft’s Internet Explorer, then be aware that there’s reportedly a major hole in the browser which could be an entry point for malware.
Chinese antivirus firm Qihoo 360 found the zero-day exploit which as yet remains unpatched, and is apparently being targeted by a group of hackers at a global level, as reported by ZDNet.
This group is apparently leveraging the exploit using malicious Office documents. When said document is opened, it fires up a web page in the background of Internet Explorer, which subsequently facilitates the transmission of malware from a remote server.
