LiquidTension Posted January 9, 2020 ID:1354922 Share Posted January 9, 2020 Hi @paul95682, Thanks for the report. To verify if this is the same issue as the original poster, could you zip up and provide us with the C:\Windows\MEMORY.DMP file please. The file will need to be uploaded to a file hosting service of your choice (Google Drive, Dropbox, WeTransfer, etc). Please provide us with the download link.

nikhils Posted January 9, 2020 ID:1354931 Share Posted January 9, 2020 Hello @paul95682 Thank you for sending the dump files. When the Web Protection layer is turned off, do you still experience issues? Link to post Share on other sites More sharing options...
paul95682 Posted January 9, 2020 ID:1354938 Share Posted January 9, 2020 I did the Clean step using your support tool, which removed Malwarebytes (I had to force shutdown because the support tool was keeping me from shutting down) . And I have not re-installed it yet. So no I have not had the problem again, but don't have malwarebytes installed yet and need to go to work. So I will install it later and let you know if the same problem exists. Did you see anything in the memory.dmp that I need to be aware of? Link to post Share on other sites More sharing options...
nikhils Posted January 9, 2020 ID:1354947 Share Posted January 9, 2020 Hello @paul95682 From an initial check of the Dump file it does look like the cause is mwac.sys and also the error in the stack is the one we are aware of. We are working on a solution for this issue and should be fixed soon in one of the upcoming updates. For now, try to re-install MB 4.0.4 and check if you get the BSOD again with Web-Protection turned on. Link to post Share on other sites More sharing options...

It will in time, however new versions are metered out to users gradually over time, but if you wish to avoid the wait you may open Malwarebytes and navigate to Settings and click on the Install Application Updates button and the new version should be downloaded and offered to you which is what I had you do. Keeps us posted if you have any more BSOD's. Link to post Share on other sites More sharing options...
