I start doubting Emsi is still so good .....I hope you are right.Splitting detection hairs between Vipre, Trend, Emsisoft, Bitdefender, Avira... statistically, it just isn't significant in the course of typical computing.
At least you know Emsisoft's Behavior Blocker\HIPS is doing a great job from the results (yellow part of column). Anyone who has used EAM\EIS knows what I mean. Emsisoft is one of the best all the way around - with virtually no major issues.
ESET bad day. That's just how it goes sometimes.
