Mine also has issues with the Premier User Interface, ever since the last update I have to run REPAIR first thing every day just to be able to run a scan. By next day it is back to not working. Since last year AVAST has had more bugs than in all the previous years I've been using it combined and I've been using it since it came out. I just renewed but if this keeps going on I'll be taking this year to find a better option with customer service here in the States
