emsisoft: great detection and fast reaction to new threats, program update in short periods so it's stable and has less bug,adding good features in every major program updates,fast scan and good scan customization options(i like the scan performance settings
) one of the best behavior blockers so it's great in dealing with zero day malwares, their staffs are active in many forums (even here in MT),i like their CEO because he is active in forums and listens to complains
kaspersky: good detection good reaction to new threats,long periods between program updates so: it have some bugs,good improvements in major version upgrades,user have a good control on settings and security, in 2015 version they did a great job in performance and zero day protection,medium scan speed,really good behavior blocker,great firewall,detecting malwares that are not in the wild and other company's are not detecting them.
webroot: new technologies in fighting with malwares,powerful cloud infrastructures,compatible with other av's,new approach in the way that a av should work so it needs some trust,i believe the way it works is the future of security software's, great support, detecting the threats that others are missing, so light, have some bugs,i'm waiting for their next major upgrade(they should work on UI, bugs, better offline protection and better detection ratio,major improvement to zero day protection)
i run all of this three along side each other on my laptop and they are working perfect.
