Welcome to the forums, Trinador! :slight_smile:

The default skin is already on the avast! user interface but if you would like more skins, follow the steps below:

First, only skins from the avast! website will work. Go there and find the skin (or skins) you would like. Download them by the instructions on the website.

Next, right click on the avast! ball in the Taskbar and then click on Start avast! Anti-virus. You should be able to install the skin you want from the avast! control panel by clicking on Menu at the top left. Then, click on Select Skin.

I hope this helps you. :slight_smile:

By the way, you can also use the Search feature of this site to find more information on skins. :wink:
