System instability after last Malwarebytes update

Recommended Posts

Running Windows 10 Pro 64, version 1909; Malwarebytes 4.0.4, lifetime license.   System is (was) completely stable.   Last night for no good reason I opened Malewarebytes and clicked on "check for updates".   An update was applied which required me to reboot the PC; the update was to version 4.0.4.49, update version 1.0.17577, component package version 1.0.793.   Since then, I've had odd things happening.   About a half hour after the reboot, I had no Internet access.   I issued an ipconifg /all command in a command window and found that I no longer had any IPv4 addresses; they were all IPv6 including my DNS server.   I ran the network troubleshooter which fixed the issue and rebooted.   Everything was fine until another half hour later when the same thing happened; ran the network troubleshooter which fixed the problem.  I then disabled Malwarebytes and left it disabled overnight.  No issues.   Today I re-enabled it again, checked for update (just in case), and left it running.  Some time this afternoon my system stopped with a BSOD crash (DRIVER_POWER_STATE_FAILURE).   

I can't prove that it's a Malwarebytes problem but it was the last thing that changed on my system (which never crashes) and the issues started happening shortly after the update.  

Is anyone else noticing anything like this?   I'm going to leave MBAM disabled for a few days to see if the issue goes away.

Greetings,

Unfortunately it sounds like you may be suffering from the same issues reported in this topic as well as this topic.  The Developers are currently working on getting this issue fixed in the next release, however until then it would probably be a good idea to keep the Web Protection component disabled in Malwarebytes.

In the meantime you can supplement your protection with the Malwarebytes Browser Guard browser extension if you aren't already using it as it will still filter out the malicious websites for your browser.  It is available for Chrome and other Chromium based browsers (such as SRWare Iron, Vivaldi, and Microsoft's new Chromium based Edge browser) as well as Mozilla Firefox and can be found here.

If you have any crash dumps (.dmp files) from the BSOD, it may help the Developers in troubleshooting the issue.  You can ZIP and attach it here if it isn't too large, otherwise you may upload it to WeTransfer.com using the 'share as link' option and post the URL for the download here.  It might also be helpful to get a set of logs from the system using the Malwarebytes Support Tool:

  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

I hope this helps, and if there is anything else we might assist you with please let us know.

Thanks

Thanks for your reply.   I've attached the file created by the Support tool and the minidump that was generated.  The memory dump is over 3GB which is over the WeTransfer.com limit.   For now I'm just going to leave MBAM shut off for a sanity check; if after a few days I continue to have no problems, I'll restart it with Web Protection shut off.

Thanks a lot for the logs/dump.  If the Support team needs the full memory dump I'm sure they will let you know and provide an alternate means of uploading it (assuming you'd be willing to take the time/bandwidth to upload a file so large; I'd totally understand if you didn't want to do so).

On the up side, based on what I've been hearing from the staff recently, it does sound as though the Developers have a handle on this issue at last and I believe they expect to have it addressed in the next update for Malwarebytes which hopefully will be arriving soon.

There's an issue with quality control and testing again. Same thing happened when v3 came out. Concerning your proposed workaround, mine is different: revert to v3.8 until at least mid-2020 by when hopefully v4 issues are ironed out.

Hello @OldMainframeGuy:

Is it still available for download

would it receive security updates?

Yes.  However, some of MB4's modules were rewritten to counter today's latest threats.

IMHO you are likely better off assisting staffers/developers with your system's instability issues for your best protection.

There was a v3.8 link from a mod somewhere on this site. I installed it directly over v4.x without issues. It's getting signature updates but of course no program updates.

There's also a v3.5 legacy version for Win7 and XP which might get better support than v3.8, perhaps a mod can comment on this specific matter?

The 3.5 version is only intended for Windows XP and Vista machines. For Windows 7 or higher, you are best served installing version 3.8.1 (download link) if you wish to revert from version 4.0. Both version 3.8.1 and 3.5 will continue to receive database updates for the foreseeable future.

@OldMainframeGuy Thank you for providing data on the issue. We hope to have a fix available shortly. In the meantime, you may wish to keep Web Protection disabled or revert to an earlier version. See here.

Nice idea, but most of us need to crack on with our daily work and not end up beta testing below-production quality software. Don't get me wrong, I've been a MWB user since v1x probably a decade ago, but v3 and v4 releases were not tested adequately and customers took the brunt.

I've downloaded and installed the "legacy" (v3.5.1) version of Malwarebytes until this all gets sorted out.   Malewarebytes 3.5.1 is telling me that "a new and improved version of Malwarebytes is available".  Is this version 4 or is it a newer release of version 3?   In Settings I have "notify me when full version updates are available" turned off so I'm not sure what this "new and improved version" is telling me.

I downloaded the legacy version via this URL which appears earlier in this thread: https://downloads.malwarebytes.com/file/mb3_legacy

Have you tried the current BETA? If you are unwilling to do that at least get 3.8.3 installed.

Use the support tool  to uninstall and after the restart click NO when it asks to install the current version.

The current KB articles will help you to set version 3.x from updating to 4.x for now

Porthos:   Thanks for the reply; the download link I found earlier in thread downloaded version 3.5.1.   With all due respect, I'd rather not be a beta tester right now.   If it was for testing things like functionality it would be one thing, but beta testing a fix for a problem that's causing BSODs is  something I'd rather not do.

My last post if you download the version I posted is 3.8.3 and the instructions to keep it that way. It is an improvement to protection over 3.5.1.

You can install it over the 3.5.1 you have now the follow the instructions to keep it that way.

Porthous:   Just FYI, the C:\ProgramData\Malwarebytes\MBAMService\instlrupdate folder is not present on my PC after installing 3.8.3 and MBAM is not issuing any notifications to upgrade.   I do have "Notify me when full version updates are available" shut off.

Then you are ok, It did not auto download the setup-file. You turned off the notification in time.

Porthos:  It's not the hill I want to die on  🙂  but eventually Malwarebytes 3.8.3 downloaded the instlrupdate folder and started nagging me to update again so I repeated the process.  Is this supposed to happen?

Exit MB from system tray and do this again.
