Testing Free English Anti-Malware On Non-English Threats

An anonymous reader writes "Brazilian technology news site O Globo posted an interesting comparison on how free anti-malware behaves against non-English threats (Google translation of Portuguese original). By using a database of over 3000 samples from Brazil's Security Incident Contact Center, the numbers are quite different from all US anti-malware reviews. While Avira achieved the best score, 78%, Microsoft Security Essentials stopped less than 14%. This can be a headache for some large multinational corporations, whose IT departments deploy US anti-malware on the entire network, but have network segments outside US with many 'unknown' threats roaming around. I wonder what the results would be in other countries."
