Review
 Pros 
Spare, simple user interface. Insulates user from confusing details,
Buy Office 2010, while making details available if desired. Good ratings from independent labs. Free.
 Cons 
Protection weaker under Windows XP. Mediocre results in hands-on malware blocking and malware removal tests. Left some threats running after alleged removal.
 Bottom Line 
If using a Microsoft product gives you a warm, safe feeling you may consider relying on Microsoft Security Essentials for antivirus protection. The independent labs give it good ratings, for the most part. In my own testing, though,
office 2010 Home and Business key, it didn't shine. Other free products offer better protection.
