Can't get rid of AvastUI

Just read the other post of yours, sounds like same issue.

Get permission to delete folders - Windows 10 Forums

Get the trial version (30 days) of Revo Uninstaller, and do a Forced Uninstall on AVAST.

Yes, i tried that as well. Avast is already uninstalled, it's a leftover folder that i can't seem to get rid of again.

What about my suggestion in post #12? Getting the trial of Revo and forcing uninstall.

Boot a Live Linux flash drive or DVD, you can delete it from there.

Avast doesn't seem to appear anywhere in revo uninstaller.

the method I've had success with for Avast removal, (and other AV Suites), in the past is to re-install the complete suite and then use either Revo Pro or the specific system removal tool from the developer to uninstall

Seems a bit of a weird way to go but it has worked in the past

Yes, i did that as well. It gets rid of the program, but there's still some folders left, that i can't seem to get rid of.

If the folders are in Program files, or Program Files (x86) then they will be owned by TustedInstaller by default and so will need the use of the Hidden Administrator to remove (or an external OS such as a Linux live ).

The problem is that due to the way that malware is these days there is an extra layer of security in place the trustedinstaller Virtual user is placed above the administrators group to get this to work.

Enable and log in as the hidden administrator [ tutorial is available on this site if not sure how ], and carefully take ownership and delete the folders concerned, obviously you should logout from, and re-hide the, hidden administrator

@Cerawy

It probably will not show in the list of installed apps because you have removed the actual app. Use the Forced Uninstall option. Browse to the Avast folder in question, choose it, and check the Advanced scan /clean option.
