Avast won't let me uninstall on Yosemite / Mac

So I installed Avast on a brand new, clean install of Yosemite. We’re now 3 hours later, I need to uninstall Avast and it simply won’t let me.

When I click Uninstall Avast in the Avast program it looks like it’s running but isn’t doing anything.
When I drag the app to the trashcan it’s again not doing anything.
When I try it with a terminal command it just crashes.

What the hell is going on with this program and what else can I do?

I would suggest posting in the avast for mac forum, a browse or search there might also reveal some info.

Cheers. Will try my luck overt here.
