I have Avast 4.5.523 on two computers, desktop and laptop. I have Avast! Simple User Interface on the desktop (It is blue and white, with 1, 2, 3, 4 on the left side). For the life of me, I can’t remember exactly what I did to get this interface (which I like) on the desktop. I would like the same interface on the laptop, rather than the “skin” which I presently have.
The Blue and White with 1,2,3 & 4 is simply a simple user interface Quick Help screen and doesn’t replace the simple user interface. There is an option to switch this off once you are more familiar.
This can also be done by changing the avast4.ini file. Check out this thread for lots of options you can set through the avast.ini file. Understanding avast4.ini file
