Hello, my avast! is doing the same thing since 2 days ago. I have avast! IS, and from time to time some shields become inactive and I have to turn off all the shields and then activate again. I have not installed any new program and before this avast! IS was running perfectly. Some of our customers are reporting the same, for example in one case the customer installs avast! 5 and all is ok, but when he restarts the computer avast! appears with the button "Fix it".
