I installed a new ssd with fresh Windows 10 pro. I was able to install Avast Internet Security and activate it on the computer fine with my license key. But for whatever reason, once in a while Avast will stop working with the error "UI Failed to Load" and it appears to be coming from the antivirus service. It gives me the option to restart it, it temporarily fixes it but the error happens again consistently.
I've tried repairing it, reinstalling Avast, but nothing seems to work. Avast was working fine for me for several months up to until now. My subscription expires in under a little 3 months. Don't think I will be renewing my subscription now...
