I had stopped on-access protection and had the circle with the line on the ‘a’ icon. I selected Updating->Program Update, trying to update from 4.6.650. It downloaded and installed the update, so it seems. But I still have the green & red update arrows in the system tray, and I still have a process running called ‘avast.setup’ with the parent being ‘ashDisp.exe’. It’s been about 15 minutes and it’s still there.
Starting the On-Access Protection hasn’t changed anything. It’s still there. But I did try to access the ‘Update (Basic)->Details’ during this time, and ‘avast! settings’ is not responding anymore.
