Uninstall Fails

I am trying and failing to uninstall Avast pro.

I first tried via Control Panel-Programs and Features the unstall started but stopped after a few seconds at:

“Launching executable file: C:\Program Files\AVAST Software\Avast\wsc_proxy.exe\svc\unregister\firewall”

I had to use task manager to end the uninstall after over 30 minutes of nothing happening!

Next I downloaded the Avast uninstall tool, avastclear.exe. Booted into Safe Mode and began the uninstall, exactly the same thing happened, after a few seconds it freezes at:

“Launching executable file: C:\Program Files\AVAST Software\Avast\wsc_proxy.exe\svc\unregister\firewall”

I have now wasted over an hour and a half of my time trying to uninstall Avast Pro. I was going to re-install but not after this. Anti virus? It’s as bad as trying to remove a virus!

Can anyone tell me how to get rid of Avast?
