I used ESET with MBAM V3 Premium for the long time
I think it's happen after update ESET in 2018 december , When i play game blade and soul in full screen mode and press alt+tab to switch to some program For example Garena and now ekrn.exe suddenly high cpu usage 25% . If i close my game and do the same as i tell you now cpu usage is 50% (25% per cycle) . My friends has the same problem but they play stream game so if i want to fix this problem i have to restart my computer every time that high cpu usage and i found that if i disabled internet protection in setup and protocal filtering the problem is resolved
