Blue screen cause by Malwarebytes if web protection on.

Recommended Posts

Hi there:)

Before posting here I ran Windbg (+ !analyze) and saw Malwarebytes listed. Over a week I tried surfing with web protection enabled and disabled on different days.

Result - No blue screen at anytime when web protection was disabled. Blue screen each day when protection was enabled.

I think that  am using the latest version of Malwaarebytes V 4.1.0

I enclose .dmp file

I'm sorry that you are experiencing trouble with the software but hopefully we'll be able to help you get it running normally.  To begin, please do the following so that we may take a closer look at your installation:

  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 Gather Logs button, and once it completes, attach the zip file it creates on your desktop to your next reply

Sure, go ahead and ZIP and attach it to your reply here.  Additionally, please try running FRST:

Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

  • Double-click to run it. When the tool opens, click Yes to disclaimer.
  • Press the Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a checkmark here.
  • Please attach the Additions.txt log to your reply as well.

By the way, you should also try running the Malwarebytes Support Tool from Safe Mode with Networking; instructions on booting into Safe Mode/Safe Mode with Networking can be found here as well as here.  If the tool runs successfully and creates the ZIP file, please restart your system and let it boot normally then attach the ZIP file to your reply.

If you can see the taskbar then it should be OK, you'll just need to browse to the folder you need using one of the links from the START menu.  If that fails then you can try launching explorer.exe using Task Manager (File>New Task (Run...)).  If you still aren't able to run the too/retrieve the logs then don't worry about it.

Please try uninstalling Zemana AntiMalware and restarting the system to see if that makes any difference.  I also noticed a sandboxing utility and a HIPS/anti-executable; if removing Zemana doesn't help, please try removing those products to see if that makes any difference with the issue (Sandboxie and Shadow Defender).

Please let us know how it goes.

Hi there:)

I tried again logging in using safe mode with networking a few minutes ago. What I should have done before was to right click the desktop and tick display icons. I was then able to run the Malwarebyte Support tool again - Sadly the result were the same with the same error message!

I tried a final time after uninstalling Zemana/VoodooShield/Sandboxie/ShadowDefender/  with no luck and same error - I can confirm that all these programs were originally disabled before I ran the support tool as I anticipated possible conflicts. I also confirmed the first time in Task Manager that no security programs were active.

Thanks, I'm sorry that none of that was successful, but at least we've eliminated a few additional variables.

I also wanted to make sure you're running the latest version of Malwarebytes in case the issue has been fixed in a recent update.  To do so, open Malwarebytes and access settings by clicking the small gear icon in the upper right, then click the Check for updates button and install any available updates, restarting your system if prompted to do so.  Once that is done please test to see if things have now improved or not and let us know how it went.

Thanks again for your reply:)

I have the latest version of Malwarebytes. I believe that  there was a new version in the last hours (screenshot enclosed). I will try again to see if the new version has resolved the issue. Hopefully it will do so. I will let you know what the result is.

This issue occurs maybe once or twice daily. I will enable web protection and try again to see if things have improved. the windbg detailed .dmp file that I sent  you indicated  an possible issue with Malwarebytes.

However if there is a crash I will check out any new minidump. There was an earlier issue with Malwarebytes browser guard but I have temporarily disabled that, as it is better to test one thing at a time.  Best wishes.

"835" is not the newest version.

I updated again just now

Still not up to date.

Please do the following Uninstall and reinstall using the Malwarebytes Support Tool

Please have lots of patience with the tool.  The first phase is a cleanup and does require a Windows Restart.
After the Restart, it may take 2 - 3 - 4 minutes till the Support tool screen shows up.   Please be patient and have faith.  Wait for it, whatever it takes.
The 2nd phase is where it offers to do a new Install.

 Let me know if that clears up the issue or not.

Is it ok to also use the Malwarebyte Browser Guard with Chrome?

Yes, but it would be better to switch to a less intensive marketing browser. @zorba




If you're not backing up your data and you're still using Google Chrome then you're just not serious about Privacy, Safety, and protecting your data. Malwarebytes is a fantastic program but you still need to back up your data and you still need to block scripts and Ads in your browser. 
If you're still using Google Chrome I would highly suggest you consider using Firefox instead. For more advanced users you might consider installing NoScript as well (it does have a higher learning curve though)

Sadly I have had several more crashes - Mini dumps again showed Malwarebytes as being a possible cause.  

I tried disabling web protection and  the MB add on for 2 weeks and have had no crashes since.

I appreciate your help but sadly there is no obvious solution - Best wishes - Howard
