Microsoft Announced couple of days ago that it will extend its support for Antimalware and Antivirus products running on Windows XP till July 2015. This is really good news for Enterprises moving and migrating from XP to newer versions as well as personal users and individuals with Windows XP.
Microsoft earlier announced that Windows XP end of support is April 8, 2014 which includes any support for bugs, security issues or any Operating system support. On top of that was the Antimalware and Antivirus signatures. Windows XP operating system launched more than 10 years ago was a very successful OS for Microsoft and was highly adopted by Organizations and personal computers. According to recent statistics Windows XP is being used on almost 30% of Desktops as per below Market share Statistics Link.
This was probably the main reason for Microsoft to Extend the Anti Malware/Virus Support for another year after the XP end of support. This extension applies to enterprise users running System Center End Point Protection, Forefront Client Security and Forefront Endpoint Protection. Also Personal users running Security Essentials will be covered as well.

This extension will not stop the XP end of support scheduled April, 2014. There will be no Security or Critical updates for Windows XP after April, 2014. Its still highly recommended to move ASAP to newer version of Windows for full support.
