Malwarebytes - causing programs to run slowly


Recommended Posts

I have been a paid user of Malwarebytes for many years (10 or more) and have installed the Pro version on all my computers. Until recently all was fine and it works well in parallel with Windows Defender. I do not feel comfortable with Defender alone.

System

Dell XPS 8930 i7-8700, 64-bit, 16 G RAM

Windows 10 home v1909

Malwarebytes Premium 4.0.4

Firefox 72.0.2

All software is kept up to date.

All was running fine until the last couple of months – I can’t tell exactly when, various programmes have been running slowly such as

Firefox – hesitates to load the homepage – which is Google advanced search. Loading subsequent pages also hesitates and loading multiple pages simultaneously often leaves a few tabs unresolved and “cannot find server”. Quitting Malwarebytes removes these problems.

When I switch on a printer, Windows doesn’t pick it up and it may require a few power cycles to get it onboard. Again, quitting Malwarebytes resolves this issue and both printers are loaded within a few seconds of their first power-on.

2 of the programmes I regularly use process large data files (3Gig+) and produce multiple data files (1,000 totalling 44G+). These used to run and write data smoothly. They now hesitate for 10 secs or more every 20 seconds or so. Quitting Malwarebytes resolves this issue.

Any programmes which check for updates (ie require initial web access) take a noticeably longer time to load than previously. Quitting Malwarebytes resolves this issue.

I have tried switching off Defender and leaving Malwarebytes running alone. Issues continue. So I have concluded that Malwarebytes is the problem here and that this started a few months ago.

Last night I ran the support tool (1.5.3.749) and allowed it to clean (uninstall and re-install direct from the web). All went well but the issues remain.

Where do we go from here? Mbst-grab-results are attached.

Thanks Porthos

Killer driver updated to latest v2.1.1359. Re-booted. Above symptoms persist with Malwarebytes enabled.

Also checked other dell driver updates. All up to date.

What happens when you just disable ransomware protection?

There is another new beta released today could you give that a try. Enable the beta settings and check for updates manually until it comes in. Restart the computer for good measure.

Hello Porthos. Apologies for the delay - other things to attend to today.

I haven't loaded the beta yet as there were a few negative reports on the beta forum - however I have been trying different Real-time protection switching and have been able to narrow the issues to 2 of the modules.

Switching off Web protection only - fixed Firefox and programmes checking for updates (the 1st and 4th/last issues detailed in my first message)

Switching off Ransomware protection only - fixed the printer loading and production/writing of large numbers of data files issues (the 2nd and 3rd issues detailed above)

I hope this will assist your determination of the problem.

After tonight, I won't be able to respond again until Tuesday - please bear with me. I can try the beta then if there isn't another solution.

Thanks and regards

Noel.

Hi Porthos

I replied yesterday but don't see my post anywhere so here it is again!

I loaded the latest version component package 1.0.810 yesterday.

All 4 issues listed above still persist although it does appear to be slightly less "sluggish". But that may be a perception.

Turning off Web protection and Ransomware protection removes the issues as noted previoulsy.

Where do we go from here?

Regards

Noel.

Now that you are on the latest version, first make sure your rebooted after the update, even though it may have not asked you to reboot.  Then see if the issue persists.  If it does, then post a new set of logs as mentioned in post #2 above.

Thanks for the logs, and just to be clear, you are still seeing the issue of sluggishness after the reboot?  Someone on the team will review your new set of logs to see if they can get to the bottom of your issue.

Hi Nikhil

See posts #6 and #10 above

Switching off Ransomware protection only - fixed the printer loading and production/writing of large numbers of data files issues (the 2nd and 3rd issues detailed above)

Switching off Web protection only - fixed Firefox and programmes checking for updates (the 1st and 4th/last issues detailed in my first message)

Hi there! Any updates or further suggestions from the team? Running with Web and Ransomware protection switched off is not going to be a long term solution.

I hate to say this but there is something seriously wrong with either version 4.0.4 or the Update or Component package.  Last week I heard from one of my client saying her PC's internet browsing has ground to a slow crawl or completely failing.  I headed over and started troubleshooting.  Tried everything I could.  Disabling IPv6, reset internet settings, cleaned up drive & registry, patched apps or OS, etc.  What seemed to have worked was uninstalling Malwarebyes 4.0.4 and reinstalling.  Until the next day, I hear a bunch of frantic txt & email saying it's even worse now since a 2nd PC in office had problems connecting beside the 1st PC from previous day.  It dawned on me that the first day troubleshooting the 1st PC, while digging for clues, I upgraded the Malwarebytes from 3.8.3 to 4.0.4 on the 2nd PC which became the 2nd PC suffering the catastrophic network failure.  I went around the office of this small medical practice and uninstalled 4.0.4 and downgraded every PC back to the 3.8.3.  I thought the problem was a fluke at this office since they are required to use Bitlocker to encrypt local drives & utilize McAfee for monitoring their Enterprise network.

Guess what?   I also have MB 4.0.x installed and running 4.0.x since 11/2019.  Just tonight I noticed my internet browsing had ground to a slow crawl.  I'm seeing ping times to my LAN devices in 400+ms for every reply.  I don't have Bitlocker on and I don't use any McAfee Enterprise agents.  Running Win10 build 1909 with all patches applied, 16GB ram, i7-5500U, 1TB SSD.  I have a lot of other clients whom I've recommended & installed Malwarebytes.  A majority probably have upgraded to the 4.0.4.  Ugh!  This is a headache I'm not looking forward to.

Just a warning about downgrading to MB 3.8.3, you'll need to have to re-enter/re-activate with the License key.  So record the key beforehands or hopefully you have it recorded somewhere.

Malwarebytes please fix 4.x soon.

Paul

Hello Porthos

This thread was dealing with my specific issues (which may well be common with others) but i haven't had a response since Thursday last - any updates on those?

I was responding to the user who jumped in on the your thread.

I have no clue why you are experiencing issues. I have no issues with my computer or with my many clients with Malwarebytes installed. But as we always remind people every system is different and can have different outcomes.

I still have a feeling it has something to do with the Killer networking software or drivers. Updated or not assuming the drivers are the ones from the dell support page.

If it was on my bench in my shop, I would uninstall all Killer software and network drivers and restart and attempt to use what Windows installs for network drivers.

But that is me and isolated in my shop and have control of the system.

Hi Porthos and team

I wish it was on your bench in your shop!

Where do we go from here? I'm currently running with 2 modules switched off - web and ransomware protection. That doesn't exactly cover what is required of MB Premium.

Regards

Noel.
