I think it’s available in both Home and Professional version but, like any other module, in Pro version it is even more configurable… specially on virus cleanning (automatic actions).
Do this:
- Control Panel > Video properties
- Screen Saver tab
- Choose avast screen saver
- Click ‘Configure’
- Inside of its configurations, choose your ‘own’ screen saver and other details.
- I could say more but I know it will be only in professional version… :-[
