In the message notification center and it did not leave the screen until you clicked x to close it? I hope this is not a new trend. I love Avast! However, the only AV messages that I want to see are:
1.) Your Virus Definitions have been automatically updated.
2.) A new version of Avast is available.
3.) Notification and or blockages of viruses and threats.
At least make the pop-up disappear within 10 seconds like the others.
