i have today the same problem after update kaspersky internet security multi device and i resolved him:
go to setup/control aplication/rules aplication and now find on list honorbuddy - right click mouse and go to 1 on top rules and.... and set trust look at tab on top window check all and set trust also when you right click on honorbuddy u can see more options that resolve all problems with kaspersky sry for my eng translate i dont have eng ver but i think it a liittle helps you.
if honorbuddy are NOT in list u can add him:
setup/additional(last option)/threats and exclusion and you see manage application and just add the path you hon..exe file after them go to like as i write on begining
good luck
edit: Play around a bit in kaspersky and write better then me and my english manual to fix this.
for me it works excelent now. only go and set correctly kaspersky like as write up.
