MbamElam.sys bsod and other issues


Recommended Posts

Hi all, would seriously appreciate some help with this!

 

Recently after rebooting my pc, it says that my pc/device needs to be repaired because a critical system driver is missing or contains errors. \windows.old\WINDOWS/system32\DRIVERS\MbamElam.sys

 

I have tried disabling the Elam thing from startup (f8), it gets on windows, but mbam can't start the service, trying it manually from services.msc says (from memory) error 507, something about being unable to validate it. Avast free's UI also doesn't load, but apparently the shields are on. Win Def is on, I remember putting periodic scanning scanning on but not the AV. What could be the problem?

 

When I load windows, it gives me an option for either win 10 or win 10 pro, "pro" is the old version, the one that can't boot, never noticed this before, I can get to login with win 10 normal but haven't tried logging in, idk of this is relevant. I also looked in the driver folder and MbamElam.sys is there, why isn't it starting up?

 

Disabling Elam from startup probably has something to do with the AV/mbam being disabled, but it's the only way I can access win 10 pro. I can get into bootmode.

Recently I have installed a win areo application, a new screensaver, and some skins for classic start menu, as well as a new update. Restore might work here, although even though system protection is on I can't find a backup, although I think there was a one from the 18th with startup repair...

Any help?

Greetings,

I'm sorry you're experiencing trouble, but we'll do our best to help.  I suspect this issue may be due to an incompatibility with Avast as recent versions of Malwarebytes have been known to conflict with many third party antivirus applications.  Please start by trying to uninstall Avast using their official uninstall tool located here, then restarting your system, then performing a clean install of Malwarebytes to see if that corrects the issues and allows Malwarebytes to start normally:

  1. Download and run the Malwarebytes Support Tool
  2. Accept the EULA and click Advanced tab on the left (not Start Repair)
  3. Click the Clean button, and allow it to restart your system and then reinstall Malwarebytes, either by allowing the tool to do so when it offers to on restart, or by downloading and installing the latest version from here

Please let us know how it goes and whether or not the issues are now corrected.

Thanks

Hi,

I restored windows 10 back to 1am this morning, and mbam works again with the service running and set to "automatic" (apparently I can't change it access is denied), and avast free's ui didn't load for a little while but then it finally did, the service works and is also set to "automatic" (can't change again). So the system seems to be working.

Is uninstalling avast/mbam the only way to find out the cause? I was thinking changing one or the other to a delayed start but I can't. Thanks for replying.

Now since you are up and running,

Can you please collect and upload as an attachment the diagnostic data using our MBST?

  • Download and run the Malwarebytes Support Tool
  • Accept the EULA and click Advanced tab on the left (not Start Repair)
  • Click the Gather Logs button, and once it completes, attach the zip file it creates on your desktop to your next reply

Most likely, yes, just because Avast is likely to still load its drivers even when disabled.  Hopefully the issue was just a one time hiccup due to an update or recent change in the system, but please let us know if you encounter any further issues.

Two other things happened on the system since then from memory, I used cmd to try to bring the sidebar back on the desktop, glary utilities wanted to update to the latest version (haven't done that since I restored), and there may have been a win 10 update. The sidebar thing was the the last thing I done before it went awol, I restarted just after, do you think that you have caused it?

Possibly, but I don't know enough about it to be certain.  It might have been a conflict between Malwarebytes and Avast as was originally suggested which only revealed itself after one of the other changes to the system because of a resulting change in the system's startup timing/boot sequence, but there's no way to really be certain if that's the case.  Just continue to monitor things and if you do encounter any further issues, let us know.

In the meantime, I did make a note of the issue to report to the Product team and I'd also like to get the memory dumps from the crash if I could.  You will find the two memory dump files listed below:

C:\WINDOWS\Minidump\122020-42812-01.dmp
C:\WINDOWS\MEMORY.DMP

Please copy both files to your desktop, then select both of them and right-click on them and hover your mouse over Send to and select Compressed (zipped) folder then upload the resulting ZIP file to WeTransfer.com, making sure to click on the circular ... button and selecting the option Get transfer link and post back the link it provides once the file has been uploaded as the file will likely be too large to attach here on the forums.

One additional note; I also noticed that you have NordVPN installed, and recently Malwarebytes has had some compatibility issues with some third party VPN applications as well because they sometimes conflict with Malwarebytes' Web Protection component so you might also try uninstalling Nord if you do experience the issue again to see if that helps.

Okay, I'll keep that in mind too.

Avast and Nord are still at the top of my list for suspects.  It might simply be that one of the products or even Malwarebytes itself updated too before you restarted, and once you rebooted, the issue emerged due to the new version.  As I mentioned earlier, we have seen issues with Avast recently, so I'm still leaning that way.

If you're using Glary to delay/manipulate the startup/timing of any of the security apps that could also be a factor, but seems less likely.  Dev/QA will likely analyze the memory dumps when they get the chance, but for now just make sure you have created a new restore point in case any more issues to show up so that you can roll back if needed without losing too many of your programs/changes you've made since then to the system.  You'll find instructions on how to create a restore point in this Microsoft support article if you need it.

By the way, while I'm no expert when it comes to analyzing memory dumps, the error indicated is DRIVER_POWER_STATE_FAILURE but doesn't seem to indicate which specific driver caused it (at least as far as I can see using BlueScreenView) and based on my research, that particular error has to do with a driver failing to respond in time to a power state change (such as shutting down or waking from sleep etc.) so it seems that it may be due to the one of the drivers not starting up/powering up in a timely manner during the boot process.  I suspect that could be due to a conflict between two of the drivers, resulting in that driver failing to load on boot and resulting in the BSOD, which would also explain why it showed that initial error about the driver being missing (assuming it was referring to the driver being expected to be in memory during startup and failing to load).

Please keep in mind that this is just my hypothesis; again, I'm no expert on the subject, but if there is some kind of bug or conflict, those memory dumps should help the QA and Dev teams to track it down.

In the meantime, as I mentioned, just be sure you have a fresh restore point created just in case, and monitor to see if any further issues occur.

You can also try to reduce the chances of any potential conflicts by configuring exclusions between the security apps.  To do so, add the items listed in this support article to Avast's trusted/allowed/ignore list, particularly for its real-time protection components, and add Avast's main program folder (likely under C:\Program Files and/or C:\Program Files (x86)) to Malwarebytes' Allow List using the method described under the Allow a file or folder section of this support article and do the same for its primary data folder which is likely located under C:\ProgramData (you can enter that path into the address bar in Explorer if you don't see it, or you can configure Windows to show hidden files and folders as described in this Microsoft support article and an illustrated guide on how to do so can be found here).

I added exlusions based on recommendations online to avast and mbam, I can for nord as well think I will find them somewhere online.
