Subject line says it all. How do I downgrade to free Avast from Premier so that I’m not spending money?
Just wait till the trial/license expires and you can revert to the free version.
OR
Remove the premier version and install the free version.
If you select to uninstall the program, one of the options you’ll be offered is to revert to the Free version.
Simply accept that offer and you’ll wind up with a free version on your computer fully registers for another year.
