well,as you already know,some of the issues that causing avast are:slowing down web surfing,very slow UI opening,can't register to our account,secureVpn(with active license)is not working,white UI and freezing many times when trying to open UI,slowing down boot time
(also reboot)and i use ssd disk,and some more but as i told you and above,all these at the stable version of a very popular vendor.Non of these issues when i tested the other three vendors(eset,avira.comodo).You release a stable version with critical issues for what???So just get serious and provide something better next time.And if do that,perhaps a lot of people come back.Did i forget to write UI window size????IF YOU HAVE something serious to responce,do it,if not,then don't bother
