End of Support for Windows XP/Office 2003, Cryptolocker, and Cryptodefense

On April 8th, 2014, Microsoft ended support for Windows XP and Office 2003. While Windows XP is extremely vulnerable now, 25% of Windows users are still running the operating system. In addition, roughly 30% of businesses are using Office 2003 despite the risks. And that’s dangerous considering the amount of viruses continuously introduced into embedded code in documents like .doc or excel spreadsheets.
