Periodic Freezing of computer

Recommended Posts

It seems either the new component or update package for MWB 3.8.3 is causing my entire Windows 10 computer to lag very badly.

There are constant delays of 3-5 seconds while trying to browse, type, or click anywhere in Windows 10. Additionally, Malwarebytes Service is constantly taking up 10-20% CPU and anywhere from 8.0 MB/s to 10 MB/s disk usage at all times, even though the app is not running any scans or doing anything at all.

Uninstalling Malwarebytes fixes the problem, but shortly after reinstalling MWB 3.8.3, the issue starts to occur again.

This only started to occur recently, so it might have something to do with Component package version 1.0.625 or Update package version 1.0.12389.

How does it run WITHOUT all those tabs open in Chrome? When was your last restart?

Malwarebytes does this even with Chrome closed.

I've been restarting constantly to troubleshoot this issue.

@spectrumfox Windows 10 Pro Version 1909 18363.329 was/is a buggy pre release cumulative update that should have been skipped. It was optional and is a "preview" for the next patch Tuesday update.

It "could" be your contributing to your issue.

I suppose that's possible, as I am currently in the Release Preview ring.

I will check to see if this is still an issue after 1909 is officially released.

The issue is still happening. I'm now running Windows 10 1909 18363.356 and am encountering the same behavior with Malwarebytes.

If I quit Malwarebytes and re-open it, it temporarily resolves the issue, but then a few hours later it randomly comes back when my computer is sitting idle.

Malwarebytes version: 3.8.3.2965
Component package version: 1.0.625
Update package version: 1.0.12491

Experiencing the same problem myself. I've even tried using the "Clean" function in the Support Tool, rebooting, and then reinstalling it.

It doesn't make a difference. There's something wrong with MB3.

Does disabling any particular component of protection help?  What about self-protection detailed above; does disabling that help the problem?

Hi @spectrumfox,

Thanks for the report.

  • How often does this issue occur? Is it every Windows session?
  • When the issue occurs, is the entire system frozen? Is mouse/keyboard input still possible? Or is the freezing limited to particular programs?
  • Does the system eventually recover or is it frozen indefinitely?
  • When did this first start occurring? Were any significant changes made to the computer around this time?
  • Is this consistently reproducible?


Please try narrowing down the protection module responsible. Start with Self-Protection.

  • Open Malwarebytes.
  • Ensure all of the Real-Time Protection modules on the Dashboard are enabled.
  • Click Settings -> Protection -> Scroll down to Startup Options.
  • Turn the, "Enable self-protection module" off.
  • Check if this has any impact or not.


If disabling Self-Protection does not have any impact, try the Real-Time Protection modules.

  • Open Malwarebytes and turn all 4 Real-Time Protection modules off.
  • Verify the issue does not occur.
  • Enable one of the protection modules and check if the issue occurs.
  • Repeat until the culprit has been identified.


Please let us know how you get on.

I've had the Ransomware Protection turned off for the last few days, and that seems to have done the trick. Will periodically turn it back on to see if the problem has gone away.

Thanks for the information. Most of the reports coming in involve Ransomware Protection. We're aware of various performance-related issues with Ransomware Protection in the latest update and will have further information available on this shortly.

In the meantime, you may need to keep Ransomware Protection temporarily disabled.

I can confirm that we have been having the same issues in our environment. We are also running Windows 10, ver. 1809. Users are seeing the gap in time between typing and the letters appearing 3 - 5 seconds later. Constant 10 - 20% CPU usage and occasional freezes that require a reboot after Event ID 7034 "The MBAMService service terminated unexpectedly".

Uninstalling MWBytes solves the problem but the problem returns with re installation. I have disabled Ransomware protection in our environment for now.

I have just found this is my problem too.  Having very slow data transfers between drives.  Bursty transfers that drop to almost zero then speed up but not by much.  Had a look in Task Manager and saw Malware Bytes was the top CPU and Disk user.  Disabled the 4 protection options and speed resumed to normal approxx 150MB/s.  While waiting for transfer also noticed that keyboard input would lag by 3 - 5 secs as others have said.

I will disable the Ransomware slider only and see what happens.

Hi all,

For those affected by the Ransomware Protection component, could you install the latest component update and let us know if this addresses the issue please.

To install the update:

  • Open Malwarebytes.
  • Click Settings.
  • Click Install Application Updates.


After the update, you should find Component Package version 1.0.627 is installed. You can confirm by viewing the About page within the Settings.

Please let us know how you get on.

If your issue is not caused by Ransomware Protection, please start a new forum topic.
