Can't uninstall Avast Online Security

I can’t seem to uninstall the Chrome extension for Avast Online Security 12.0.562. I have removed it from my Chrome profile using the trashcan icon, and it’s not there anymore. But when I add a new fresh person profile in Chrome and check the extensions tab it still pops up. Restarting Chrome and my Mac doesn’t help. Wtf is going on? >:(
