New skin

When it will go to have new skins, would be very good if 2000 professional had skins with the interface of windows.

? There is already one skinless interface that uses native Windows themes…

But an interface as simple, the former ones,a well easy and friendly interface.
It does not have as to make improvements in the simple interface of avast? leaving more beautiful?

Well skinless interface is just fine imo. Very simple to use and nice design in its own way.
