Let me make a suggestion. Please enable selection of two products and you'll actually get a more practical cumulative result from all voters!
Eg. I love EIS(EmsiSoft), BTS and KIS almost equally but there are some factors in each that make me give a 5% positive margin to one and the effective negative to the other. Selecting 2 products will provide more priority to protection and remove the least preferred from the results.
Coming to the topic, I'll say
EIS
superb definitions + dual engine + behavior protection (almost flexible/ select if you'd like to make some decisions in advanced cases)
BTS
superb definitions + aggressive threat control + .. (this one is aggressive even in default mode/ quite less direct user decisions possible/ a bit buggy currently)
KIS
next superb definitions + advanced malware removal + application control/system watcher .. (highly customizable/ least FPs/ mostly does a good job on its own/ however, it misses rare malware if it belongs to low restricted list etc./ if automatic is disabled, certain processes generate tremendous amount of popups and becomes a tough job attending each)
I don't want to dispraise any other product, but MalwareBytes is an overhyped product, good for complementation. Some important components like AE, AR etc are included to make prospects feel that they're getting a bigger family of features, while the main protection is not worth keeping as a standalone!
Hence, I would recommend one to try out EIS and KIS both to seek the best guardian.
