BSOD after updating. "HWEA_UNCORRECTABLE_ERROR".

I’m getting “HWEA_UNCORRECTABLE_ERROR” after installing the lastest Avast via the GUI. Also after removing and re-installing I get this “HWEA_UNCORRECTABLE_ERROR”.

It happens just before the Windows Login Screen.

I think when I will use the offline installer I will still get this error too, so I won’t even bother trying it, getting tired of doing a System Restore all the time. Hopefully this will be fixed soon, I can do a couple of days without Anti-Virus.

You can’t install a newer version through the GUI, only update a existing installation.

What OS/SP ?
What exact version of avast ?
Is there any other security (related) software installed ? (or was there)

  1. Windows 10 Anniversary 64-bit
  2. Avast 12.3.2279 (2016-08-16) (upgrading to latest (which I guess is 17.1.2286 (2017-02-07)))
  3. Only CCleaner and Windows Defender.

What I have done is upgrading, which caused a BSOD.
Uninstall, reboot, reinstall, which also caused a BSOD after rebooting just before the Windows Login Screen.

So my guess is that the offline installer will do the same.

How exactly did you uninstalled avast ?

Do you have (or had) e.g. Comodo installed ?

I used AvastClear.
No.

Well, avastclear doesn’t remove everything.
Only a manual removal does.

I suggest to remove avast completely.
Do a thorough clean-up of the system and perform a true clean installation of the latest avast version.

I already did a complete removal from Avast uninstaller before I used AvastClear.

See my previous reply.
avast is not completely removed that way.

Sorry I have to be more clear, I used both, the uninstaller and AvastClear.

EDIT: I could upload the Minidump files…

See reply #5

What about it? You are not really helpful, I uninstalled and used AvastClear…

Clean Install of Avast:

Followed your steps (reboot in save mode, uninstalled Avast, reboot again into save mode, run AvastClear) and followed your install instructions, installed with offline installer, still BSOD after reboot, just before the Windows Login Screen.

Not exactly my instructions but, in your case, the error refers to a driver incompatibility.

Hmmm don’t think so, because it doesn’t happen when Avast is not installed.

Hi
It is the same for me : Win 10 + Avast 17 (install after Avast clear) = BSOD “WHEA_UNCORRECTABLE_ERROR”
If I uninstall Avast everything wotks well.
Definitively an Avast BUG.
Eveything was working well with Avast 16

can you please compress \windows\memory.dmp (e.g. 7z archiver) and upload this dump somewhere? (Avast ftp: https://www.avast.com/faq.php?article=AVKB160)
thanks

upload started : MEMORY_Dump.zip (estimated upload duration 1h)

Thanks

Hi, I can see unloaded Bluestack hypervisor from dump, is the bug somehow connected to Bluestack emulator execution?

Yes this could be, I had BlueStacks also installed, but I don’t use it anymore and uninstalled it, I’m using MEmu to Emulate Android now, much better. Maybe I will try to install Avast later but I have other things to do now first.

I will post back if Avast install alright now.
