Free antivirus issue

[Trevor31]

Hi,
I was using the free antivirus for quite a while until my Windows 22h2 update.

Last evening I was updating my Windows 11 for the latest release, 23H2.

After this update, I got the blue screen of death with message stop code page fault in non-paged area what failed aswArPot.sys

The PC was restarting with the BSOD showing the same error.

How can this be sorted, please?

Many thanks

There is not enough information at all. The numbers are important in the BSOD message. For developers, it would probably be worth attaching a minidump from the folder C:\Windows\Minidump It is also important to specify the avast version.
There can be many reasons for the malfunction. This is a malfunction of RAM, file system corruption, an unsuccessful update or incorrect drivers. Depending on the reason, you need to choose a solution. It may be necessary to roll back the system update. But first it would be good to try to boot the system in safe mode. If it works out, you can simply uninstall avast to boot the system normally. But before deleting avast in safe mode, you can also run a check of RAM (press win+r enter the command mdsched.exe) and file system (run cmd as administrator and execute chkdsk c: /r). If there is a problem in the file system, then deleting avast may not be necessary. In any case, it is necessary to check the RAM and file system in order to exclude their malfunction options.

Hi Nom,

Thank you for the prompt reply.

I booted into safe mode and did a system restore to Windows 22h2.

The computer was back to normal, and then I uninstalled Avast Free Antivirus.

I am now going to update Windows to 23h2 and also created a restore point to see what happens.

I will then try installing Avast again after the Windows update.

How do I insert an image here of the BSOD for you to see?

Many thanks

After the rollback of the system, minidump probably deleted. I am not an expert on minidump decryption, but according to the bsod message, i can say that most likely the system update was incorrect. Avast files or registry entries may have been corrupted during the update. And the reasons may be memory and hard disk failures. Maybe it's just a failed update. I doubt that the avast driver is to  fault. This is some kind of system failure. Probably after updating and reinstalling avast everything will work.

Hi,

I have now updated Windows 11 to 23h2 without Avast installed.

Did a search for the file on google aswArPot.sys and got this https://www.file.net/process/aswarpot.sys.html

memory and disk are all working with no errors.

I am attaching a screen shot of the BSOD.

It is a most likely the avast driver which created error after the update to 23h2.

Many thanks

You're welcome.

When installing avast on an updated system, does it issue a bsod again? Can you do a complete removal of avast with a specialized utility and then do a clean install? https://www.avast.com/uninstall-utility?ysclid=lom8rmc1tn711221243#pc
Perhaps this is some kind of software conflict and not the fact that avast is to blame. Perhaps microsoft has released a crude update, as often happens.
