Back to Avast free antivirus

I downloaded the trial version of Avast internet security which is now expired. I can not find how to revert back to the free Avast antivirus program. Do I have to delete the Internet Security and re-download the free version?
Thank you for your help.

Unless you started out with the free version and then took up the 20 day AIS trial (which is/was meant to have a way to revert), then you will have download the avast free version (saved to your hard disk), uninstall AIS and reboot. Now you can install avast free.

Do it in that order, first get the avast free version before uninstalling AIS, so you aren’t unprotected when you go on-line.
