I am a newbie to this forum and program and posted some of these suggestions in the Beta section but I think maybe they should be here.
First, when scanning or something needs attention, the tray icon should be animated.
Second, when a scan is in progress there should be a progress bar or circle that shows the progress of the scan rather than a constantly rotating circle. Also, there should be buttons to stop, pause, or resume the scan. I do not see any.
Third, there should be a form of web protection against malicious websites than can be turned on or off.
Fourth, some competitors have a feature where the initial scan is the longest and subsequent, are shortest.
Finally, this is more of a question. The more av engines I use, the longer the scans take?
