Logged in as Admin, but still won't let me remove add ons from my browsers

Avast Free Antivirus / Premium Security

I am logged in as the admin, but it won’t let me remove a bad browser add on because it thinks I’m not logged in as the admin. But I AM! How do I fix this so I can remove the add on?
I just have Windows 7 and it won’t work for any of my browsers (IE, Firefox, or chrome)
