Hi all,

Got a weird problem here. An old friend of mine (86+) is using a laptop
with W10 Pro 64b. Since a few weeks the 1803 update is knocking on the
door, but it won't install as Avira is in the way. So I uninstalled
Avira. Didn't work, So I uninstalled Avira completely with Revo
Uninstaller Pro. Also deleted the lot of registry keys. I thought.
The 1803 update won't still install because of Avira. But it's no longer
there, the folder C:\Program Files (x86)\Avira does no longer exist.
What I saw with Regedit that there is still a key in the registry,
inspite of deleting it with Revo. It's
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Avira. It contains a lot of ****
and some sub keys.
I guess that's the reason Windows won't update the 1803 version.
But I can't delete that key. Even when I ran Regedit as administrator,
it won't let me delete that.
How can I get rid of this?

And - perhaps a warning of using Avira? I'm not so keen of it by now.

The preferred approach on AV products, is
to locate the "Cleaner" each AV maker has.
You search around until you find it. The web
page the cleaner is on, will explain how to use it.

1) Run regular uninstall. Reboot.
2) Run "Cleaner" application. Reboot.
3) Now, the product should be gone.

The reason for the "Cleaner" to exist, is to enable
"re-installation". They don't want to admit you'd
ever want to remove a product, because the product
sucked.

Not all "cleaners" are as good as one another. There
are at least some cleaners, which remove every trace of the
product from the registry.

While you could use the SYSTEM account or TrustedInstaller
token, that treatment is reserved for "actual malware".
Because actual malware is not systematic in naming
convention.
