For the 2015 version over here, the free protection package will periodically prompt you about other products and services Avast provides. There is a box to uncheck to stop receiving the notifications, but it's greyed out in the basic level - only available after you pay for an upper tier. You can change the time the popup is displayed to 0 seconds as a pseudo-workaround, but it still pushes random things that you have to close. It's one of the very shady things Avast has started doing within the last six months - the online shopping tool that it automatically installs and you actively have to search for how to remove is basically spyware. Ironic, given the sort of program Avast is.
