There was only an earlier version in a Master storage folder ready for me to install but I did not do so. I was contemplating doing it soon but have been relying on the the built in Windows Defender. I setup my wife’s new computer at least two weeks ago. I checked the date and time of the folder of the latest version of Avast Free and it said 16/11/2017 at 11.55 pm. So what enabled the download and install. I became aware when the icon appeared on the taskbar. I clicked on it and was informed to restart the computer. The registration stated 29 days left. I have been using Avast Free in various versions on three home computers for a number of years and have never had this occurrence.
