New user
when i open avast it does a memory test then it opens up a user interface then behind that it looks like some sort of radio
on the screen is all of this normal or should it open in a different window
That’s the default appearance of the Simple User Interface - i.e. yes, that’s normal. If you don’t like the appearance, open the menu (by rightclicking on the window), choose “Select skin” and you can switch to another one. Many additional skins can be downloaded here.
If you don’t like the skins at all, open the menu again, choose “Settings”, uncheck the option “Enable skins for Simple User Interface” on the first configuration page and restart the avast! program. You’ll get a skinless (“standard Windows”) appearance.
