Cannot delete Avast Software key from registry

Specs: Windows 7 Ultimate, 32 GB
Hi!

Been trying to remove all traces of Avast from my Windows7Ultimate pc.

First thing I did was to use Avast's uninstall utility.

Then I searched the entire computer (C and D drives) for anything 'avast' and
deleted 151 files.

Then I searched the registry and deleted anything 'avast'.

But there was one key I could not delete from the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\AVAST Software

On another forum I found an Avast Software folder sitting in,
File explorer -> Program Files -> Common Files -> Avast Software
and deleted it.

Still cannot delete the registry key.

I found an Avast Software folder sitting in Task Scheduler under Task Scheduler Library

When I tried to delete it I got, "The directory is not empty" error, but there's nothing to the
right where tasks would be listed.

When i right-clicked the Avast Software folder and tried to Display All Running Tasks I got,
"Task Scheduler service is not available. Verify that the service is running."

I checked Services: Task Scheduler is started.

And now I'm stumped.

How to:

1) Remove the Avast Software folder from Task Scheduler/

2) Remove the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\AVAST Software key?

Thanks!

You should have used Revo Uninstaller. I'm not sure if it's too late or not, but it's worth a try.

CCleaner-Slim might be helpful as well.

I would run them, reboot, then run them again.

@riider:
CCleaner is owned by Avast:

As for Revo, it seems owned by Piriform which in turn is owned by Avast.

@Johnw:
Good lead! I will give it a run! Thanks!

I've been using these on all comp's that I fix, for about 10yrs JohnDohe.

Run both of these, in this order.
1: Wise Disk Cleaner ( Run the 1st three tabs, left to right. I use default settings, leave boxes that are unchecked, unchecked ) Reboot when finished.

2: Wise Registry Cleaner ( Only use Registry Cleaner & with default settings. Don't use System Tuneup, that is for Experts, you really have to know what you are doing ) Reboot when finished.

@ Johnw

Really appreciate your links and all!

But alas . . . The registry key HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\AVAST Software
and the Avast Software folder sitting in Task Scheduler under Task Scheduler Library sadly remain.

Neither Wise Disk Cleaner, Wise Registry Cleaner nor Malwarebytes RegASSASSIN were able to delete either of these :-(

Any other suggestions?

Thanks!

Just had a look in my W7 & W10 comps & they have those entries as well, I'm not concerned.
You probably have done as much as you can.

How about installing the software again, maybe uprading it, as long as it is working correctly again, and then try to remove it ... Either the same way you tried earlier, or just not; any other way may have more success. I mean, it's just software ...

Behold the fact that the registry key may never want to be removed. I don't agree that is good, but I'm sure some software out there does that. This is the kind of stuff that can only be fixed by Windows re-install. But I would not re-install Windows to only have these kind of things fixed.

Installing Avast again and then using the Unistall utility from AVAST may work.
https://www.avast.com/en-ph/uninsta...

Or remove it with this utility https://www.revouninstaller.com/
