Greetings, fellow avast!ians:
I asked about this issue in the beta forum a couple of days ago. Appears to be an intended behavior, according to the brief exchange found here:
http://forum.avast.com/index.php?topic=122735.0
I really do believe that at least a checkbox option to automatically dismiss the popup after a user-defined number of seconds if no threat is found is something that the development team should consider. I understand the intent here, but once the scan is complete, we don’t really need to know that it occurred if it turns up no problems, and in any event a record of it is, by default, available in the logs section.
Regards,
Crashman
