uninstall Avast

hello
I have been given a new anti virus program by my employer
I have removed Avast from my computer but there are some registries still here. I’m unable to delete them they give me an error. The path for these files are Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Avast Software.
I am running Windows 10

I have run the un-install programs from the Avast website

Any help would be greatly appreciated

Thankyou!

Does this mean that Avast have still not fixed their uninstaller avastclear.exe to completely uninstall the program and registry entries?
What is the timeframe for this to be completed by the devs?
