Microsoft’s Security Essentials and Forefront Endpoint Protection failed to earn a “certified” status. Both failed to pass an evaluation by a Germany security software testing organization. Many of the malware samples that AV-Test used were never encountered by millions of Microsoft systems. Microsoft says 94 percent of missed malware samples were not encountered by customers. The company says it prioritizes how it provides protection based on the prevalence of threats, not on the number of threats it finds. Microsoft: “We’re committed to reducing our 0.0033 percent margin to zero””]
