Blue screen of death after recent update

[markdeassis]

I have recently updated my Malwarebytes just to have it crash constantly in the last hour with this error: mwac.sys malwarebytes driver_irql_not_less_or_equal. This is something that happened a few times back in January and I've seen some threads about it. After an update, the problem stopped. My concern is: I have never had the experience of a BSOD because of a program, much less an antivirus, only "not responding" errors, and this has caused me to lose projects and files.

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

I suggest turning off fast startup in Windows. Then restart.

I would  also recommend creating exclusions between Malwarebytes and Your AV to help prevent any possible conflicts or performance issues.  Please add the items listed in this support article to Your AV 's allow list(s)/trust list(s)/exclusion list(s) particularly for any of its real-time protection components and likewise add Your AV 's program folder(s) (likely located 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 may need to show hidden files and folders to see it).

 

Please also refer to this support article which lists several known applications which conflict with the Web Protection in Malwarebytes currently, which includes BitDefender™ AV products

I've done what you said and I'll see if the BSOD happens again.

If you disable the web filtering feature in Bitdefender or the Web Protection in Malwarebytes, that should eliminate the BSODs.

A new beta has been released which addresses some BSOD issues.  To install it, open Malwarebytes and navigate to settings by clicking the small gear icon in the upper right, then scroll down to Beta updates under the General tab and enable the option to install beta updates, then scroll back to the top and click the Check for updates button to have it download and install the new beta, then restart the system once it completes and test to see if the issue is now resolved.

Please let us know how it goes.

Thanks
