If your agency is still running Windows XP on its desktop computers, Microsoft has published a new reason to switch to Windows 7 or 8. The company’s latest Security Intelligence Report shows XP computers are hit with malware infections at twice the rate of machines running the other OSes. More than nine percent of XP machines were infected through June of this year, versus five percent for Windows 7 and 1 point 4 percent for Windows 8. Microsoft reports, overall fewer computers are encountering malware attacks, so fewer are succumbing to them. The report shows enterprise computers tend to be better protected than individual consumer ones. Microsoft is ending support for Windows XP this coming April.
