When your Avast trial version expires you do not get an automatic option to convert to the free version.
However, as soon as you start uninstalling the trial version, a pop-up window appears that gives you the option to convert to the free version. Just follow their instructions.
I have done this from Windows XP. Go to control panel, choose Add or Remove programs. Choose Avast and remove program. The pop-up window should appear soon after.
