Problem with Avast Clear Uninstall utility
« on: July 26, 2016, 02:11:50 AM »
I'm having a problem removing Avast completely.  A few months ago, I uninstalled it via the Windows 7 control panel.  Recently I updated to Windows 10, and today I got a popup message from the Avast upgrade utility, which was a surprise since I thought it was uninstalled.

I did some searching and found & downloaded the Avast uninstall utility here: https://www.avast.com/uninstall-utility  I ran it and followed the prompts to boot into safe mode. (It was definitely safe mode. Everything was huge, and it said "safe mode" on the screen.) It seemed to complete without errors, and prompted me to reboot. It did gave a message that some components might not be gone until a second reboot, but that didn't look like an error.

After that I got stuck booting into safe mode endlessly. I managed to get back into proper Windows by editing the boot tab in msconfig.

However, after I booted back into normal Windows, I immediately got the "Complete Windows 10 update" popup from the Avast upgrade utility.

Also, when I look at msconfig, Avast Clear Uninstall is still listed as my default OS. I tried deleting it, but it came back.

How do I get rid of this software?  Any help would be much appreciated.

Remove avast manually.
- Delete all files
- Delete all folders
- Delete all registry entries

Thanks for the suggestions!

It seems to be fixed now. I figured out how to get rid of the uninstall tool as default OS (my problem there was neglecting to set Windows as the default OS before deleting the Avast Clear OS option) and once I did that and rebooted, the upgrade popups disappeared as well. My guess is that something went wrong and kept the uninstall tool from cleaning itself up on restart after running it.  There are still a couple of registry entries for Avast, but they're all under firewall rules so I think the software & update popup utility are gone.

You can't delete the default OS until you've set the default to something else you system can boot to. :)

Hi.

I'm having the same problem as daisywreath (when I turn on my computer, it asks me which OS I want to run, Windows 10 or Avast Clear Uninstall, as if Avast clear were an OS). I search for remaining files and folders on C disk and Search option, but I don't see any left. When I go to System Configuration, it shows both "OSs", and it gives me the option to delete Windows 10, but not Avast Clear.
I did what daisywreath did (set Windows as the default OS in msconfig, delete the Avast Clear icon and then reboot), but it still gives me the two OS options when I turn on the computer.

My question remains the same: How do I remove Avastclear as an OS (or all together, for that matter).

Thanks greatly for your help.

Sounds like Avast clear never finished running.
What if you choose Avast clear as the OS to boot into ??? What happens ???
Have you tried re-running avastclear.exe ???

I've got exactly the same problem as jillgarnet. avastclear.exe simply disappeared when I ran it, but it still gives me the two OS option. I can't find it anywhere else in the system so I can't delete it. But when I try to run the Avast clear "OS" it loads  the safe mode of Windows and says "failed to run the programme"...

Posting in an old topic is never a good idea. Please start your own topic and describe your problem in detail
