[QUOTE="Andy Ful, post: 928036, member: 32260"] Because the AVs share signatures, it is improbable that Trend Micro could miss so many one-month-old samples. My guess is that the difference between AV-Comparatives and AV-Test follows not from old but rather one-week-old samples (medium old samples in Malware Protection tests). These missed samples were probably blocked in the wild as fresh samples by Trend Micro's prevalence or reputation rules, but Trend Micro did not make detailed analysis in the cloud (other good AVs do it). So, contrary to Trend Micro, other AVs could already have the signatures for such threats and scored well in the AV-Comparetives Malware Protection tests. Edit. The samples from Malware Protection tests have several times smaller infection rate as compared to fresh samples. So for most users, the overall protection of Trend Micro is probably similar to Kaspersky and F-Secure. [/QUOTE]
