Windows 7 is four to five times less vulnerable to malware infections than is Windows XP.
Those are the findings of Microsoft's latest Security Intelligence Report (PDF), which detailed in depth the state of software vulnerabilities, exploits, security breaches, and malware in 2010.
Overall, the study found that infection rates for newer Microsoft operating systems with the latest service packs are consistently lower than those for older OSes, giving Windows 7 and Windows Server 2008 R2 the highest marks for security.
Looking at the number of reported infections per 1,000 computers, Microsoft found that Windows 7 64-bit had the lowest number at 2.5, while the 32-bit version had 3.8.
Windows XP with SP3 came in with 15.9 infections per 1,000, while XP with SP2 had the highest number at 19.3. Breaking down the numbers, Microsoft's stats mean that Windows 7 is around four to five times more secure than XP.
