Updated Avast and it installed 2014.9.0.2006. I run windows 7 and use Chrome as a browser. Computer was totally unresponsive, as was Avast which totally disappeared at one point and gave no indication it was updating. After a complete afternoon (Yes, afternoon!!), many reboots, and much patience, I can now get online but still have the yellow exclamation mark saying I need attention "Some Shields are Off" The resolve and turn on buttons are totally unresponsive. What gives with this new version? How do I fix this?
