I have set a password to the admin console in Avast. I am using Avast Internet Security 2015. I can’t log in or change the password. It has me locked out. Need help fixing this please.
You will need to perform a clean installation of avast.
How do I attempt a clean install if I can’t uninstall the program because it has a password?
Hi b.75 
Clean install :
Download the Avast! Uninstall Utility to your desktop.
Download the correct version of Avast!
Avast! Free
Avast! Pro
Avast! Internet Security
Avast! Premier
Disconnect from the internet.
Uninstall Avast! via control panel.
Run the Uninstall Utility and accept the reboot to safe mode.
Once complete reboot your system.
Reinstall Avast!
