???On Avast download site for Skins states that need to have fast Graphics Adapters otherwise may slow down avast considerably, how can i find out if i have suitable Graphics Adapter ? Many thanks, Roseman from Downunder in Oz
Roseman, the best will be just trying… if your computer is not that old, you won’t have problems with performance. 
You could tell us what graphics card you have ?
If you are currently using avast skins (there are three with the installation, try each one) without any problem then you are likely to be OK. If you haven’t got a fast enough graphics card and the skin use is slow you can always use the no skin option.
