Malwarebytes causing freezing/slow response

[xerophytes]

Happens quite a lot lately - in fact - almost every time I log into my computer.

When the computer switch on, it was okay. Until I do a lot of video watching and streaming like in Netflix and/or multiple tasks in Chrome. 

Then I turn on my task manager and notice that the freezing correlates to an increase activity with malwarebytes, hogging the memory, then once it's gone, the freezing unfroze for awhile, then it repeats. And then my wifi will get disconnects (not sure if it is connected at all).

After learning that, what I did is I quit using Malwarebytes. True enough, for the whole night I have been using and streaming, no issue.

I have Premium, and such a shame that this is causing my computer to go shite.

Thanks.  Your logs show that you're using OpenVPN, and it is possible that it is conflicting with the Web Protection in Malwarebytes which might be the cause of the performance issues.  Lenovo Vantage/IMController is also known to sometimes cause performance issues on some systems, though I do not know if it is related to your specific problem with Malwarebytes.  I also noticed that you have quite a few memory dumps which indicates that there have been a lot of crashes recently.

If possible, I would like to collect at least a few of those memory dumps for our team to analyze in case it helps them to determine what might be causing this issue.  The memory dumps are listed below:

Recent Windows Crashes
========================================
C:\WINDOWS\Minidump\032621-60359-01.dmp
C:\WINDOWS\Minidump\032621-56375-01.dmp
C:\WINDOWS\Minidump\032721-36812-01.dmp

C:\WINDOWS\Minidump\042221-37015-01.dmp
C:\WINDOWS\MEMORY.DMP

Given how many there are and the how often they're being created, it seems likely to be related to the issue you've been experiencing with Malwarebytes.

Please copy the above listed files to a location you have full access to such as your desktop or your downloads folder, then select all of them and right-click then hover your mouse over Send to and select Compressed (zipped) folder.

Once that is done, upload the resulting ZIP file to WeTransfer.com and selecting the option to send the file as a link as detailed below:

1. Visit WeTransfer.com and click the Manage settings link for cookies shown on the lower right of the page as illustrated below: link for cookies shown on the lower right of the page as illustrated below:

   

2. Click on Your Privacy Choices on the menu on the right as shown in the image below:

   

3. Click on No Thanks on the upper left, then click Save on the lower left as shown in the picture below:

   

4. Once that is done, click the circular (***) button as shown in the following image:

   

5. Select Get transfer link as shown below:

   

6. Scroll back up and click the circular plus (+) button highlighted in the image below:

   

7. Browse to the location where you created the ZIP file containing the memory dumps and select it then click the Get a link button
   

8. Once the upload completes, copy and paste the link it provides here into you reply so that the team may take a look at the memory dumps
   

Thanks

Once you're done with that, I would also suggest restarting your system as some remnants of Malwarebytes are waiting to be removed on system restart from when you uninstalled it.

[exile360]

There is also one more thing to check while we wait on the dumps if you're willing to try it to see.  Depending on when they are scheduled to run, scheduled scans in Malwarebytes may be the cause of the performance issues.  By default, Malwarebytes is set to run a scheduled scan once per day, usually around 2AM~3AM, but if the system is off at that time, the scheduler will run the scan as soon as Malwarebytes is next able to, meaning around the time that your next start your system after a missed scheduled scan.

You can modify this setting so that the scan either takes place during a time that the system is available and won't be inconvenient for you, or you can configure it not to automatically run missed scans.

Details on the settings for the scheduler can be found in this support article.  The option for recovering missed scans is located under the advanced settings for the scheduled scan and is called If missed, scan at next opportunity.  If you toggle that setting off using the provided toggle and click Save, the scan will no longer automatically run whenever Malwarebytes is next running so that it isn't as likely to occur when you are busy using the system.

HMMMMM.....

I was using my computer the past ~ 4 hours and it appears very stable, despite of me streaming, with open multiple tabs on Chrome.

So, I don't know what happened, but this seem to be 'fixed'. Wondering if 'checking updates' fixed this problem. But anyhow, I will do these steps you mentioned.

 

Hang on.

[xerophytes]

Dumps:

[exile360]

It is possible.  There have been several recent updates for Malwarebytes, plus since you removed/reinstalled it, it also could have replaced one or more corrupt data files.

Please continue monitoring the situation and let us know if it shows up again, but hopefully it is fixed.

In the meantime, I'll make sure that the dumps you provided are passed on to the team for analysis; thank you again for providing them, it is very much appreciated.

[xerophytes]

OH WAIT

I lie.

Checking my task manager, and my task bar, the malwarebytes was not on.

[xerophytes]

So the reinstalled malwarebytes did not help.

After having it run, I was having the same freezing problem. I have to quit the program.

[exile360]

That is unfortunate, but thank you for letting us know.  Can you test to see if just disabling Web Protection also eliminates the issue?  To do so, right-click the Malwarebytes tray icon and click where it says Web Protection: On and click Yes if prompted by User Account Control.

[xerophytes]

So what I did is I manually run a scan, at least for the past 30 minutes, no problem and no acting up. I am not sure if the hogging of memory was due to its attempt to do a scan. Will wait and see.

[exile360]

To make certain you can delete the default scheduled scan for now while you're testing, then see if the issue returns without any scheduled scans set.

[xerophytes]

Left my computer on for hours. Streaming netflix for a few hours. No problem.

So my best guess is that malwarebytes is attempting to do a scan.

[exile360]

Yes, that definitely seems likely.  Please keep an eye on it and let us know if it returns, and if you haven't already, adjust the scheduled scan options as I mentioned above to ensure it doesn't try to scan when you don't want it to.
