Scanner Message pop-ups sometimes occupy 1/3 of my screen- is ther a way for them to run in background or be hidden?
Yes, not to have enabled them to start with, sorry couldn’t resist.
- Standard Shield > Customize > Advanced - ‘Show detailed info on performed actions’ this option is off by default, so it would appear you have been tweaking avast without knowing the effect it will have. This function is also on the Web Shield and Internet Mail providers so you should also check those.
