Default Stubborn Avast

Good Morning All

Yesterday my wife somehow accidentally (? whilst updating C Cleaner ) managed to install Avast antivirus to her laptop.

Not wanting this she removed it using Revo Uninstaller including the 'advanced' scan facility also.

However - Avast is still showing up as a Startup program even though it does not appear in the main program list in Control Panel and is set in Services as 'automatic' and 'running'.

I cannot disable or remove it from the services list even though I have unticked it in msconfig Startup.

What am I doing wrong here please and how should I proceed further?

Regards

Roy

Before uninstalling an AV program, its necessary to stop it running in the background as running services/programs cant be uninstalled.

Download Autoruns.

https://docs.microsoft.com/en-us/sys...loads/autoruns

Run it in Administrator mode. Select each tab in turn and untick any entries for Avast. Reboot the PC.

You will likely need to use the Avast uninstall utility.
Follow directions exactly:

Maybe just reinstall Avast and then download the Avast custom uninstaller from their web site.

Thanks to all for your replies.

I'm afraid I am not having much success :-

1. Autoruns 'denies access' to attempts to untick any Avast entries - doing it
as an Administrator.

2. Re-installed Avast and downloaded the Avast Clear uninstaller.

Opened computer in Safe mode as instructed but trying to open the
uninstaller showed message :-

"The stub cannot run uninstaller/update executable"

'C:\users\Sheila\AppData\Local\Temp\-au_iup.tm~a0160\instup.exe'

( code 0x10b )

What shall I do next ?

Regards

Roy

Maybe contact Avast support might be the quickest solution.

I've just seen the following article which deals with a very similar (almost identical) problem to yours Roy. Perhaps it will be useful for you:

I've just thought of this. You mentioned that your wife used Revo Uninstaller and it didn't get rid of Avast AV fully. I use Revo too and I also have Geek Uninstaller which I use often. I'm only mentioning this in case you're wary about using it. It's a good program which has always worked well for me (they both do in fact) and I think you can be confident using Geek if you try the method shown in the article in my link.

You may need to take ownership of Avast to use Autoruns to remove it.

While you haven't said which version of Windows you are using, I use the first one on my Win 7 machine and the second on my Win 10 machines.

https://www.sevenforums.com/tutorial...-shortcut.html

https://www.tenforums.com/tutorials/...dows-10-a.html

Open Windows Explorer - Windows C: - Program Files - right click on Avast then click on Take Ownership and then try Autoruns.

If that doesn't work, Use the Registry Editor. The procedure is the same for all versions of Windows. Create a Restore Point in case of accidents. In W10 go to Search and type regedit. Right click on the link and choose Run as Administrator. In other versions go to Start, click on Run and type regedit. Click on the Edit tab and on Find. Type Avast into Find What. Click on Find Next. Delete the key it finds and repeat until you've removed all the entries and reached the end of the Registry then reboot. This will take some time to complete as there are a lot of keys..
