Hi Fhurst and welcom (and keep zen !)
I'm just a new avast! user and I can say you it's a great product.
For avast! "annoying" display you have just to setup it on "silent mode" (standard shield protection/advanced), for the rest I'm sure you'll have very good advices on this forum ! 
Where is this setting? Are you talking about the sensitivity slider for the Resident Shield, because if you reduce the sensitivity you also lose a level of protection at the same time?
I want that protection but, without it showing me the progress of it's scan, which by the way is impossible to read at the rate it is scanning anyway? If this feature is supposed to make FEEL secure by just seeing it's progress, then I say get rid of it and don't spare my feelings, because I don't need this type of visual imput.
Each time it appears I have to stop what I am doing because it rises up on top of everything and obscures it. I can't read, select, scroll, or think because of this obscuring distraction.
It is so annoying and distracting that I forget what I am doing and I can't handle it anymore. I am about ready to uninstall Avast! if I can't stop it.
Please understand, I am not angry, I'm just so distracted and depressed, that I just don't know how to handle all this. My children are in college and they need this computer in order to do their assignments, or else they have to use the one on campus, when one is available, and they return home so late and exausted that I'm afraid they will have an accident on the way. My cousin did just that, a few years ago. If it wasn't for their needs, I'm so frustrated that I would like to take a hammer to this thing.
