Extremely high memory usage


Recommended Posts

Ok. I am an unhappy cookie this morning.

Woke up to find that for some reason, the Malwarebytes service's memory usage keeps constantly increasing at an alarming rate (makes the PC unusable within 10 minutes of use, no joke) without there being any activity on my computer except me typing this in Notepad, because of the problem Malwarebytes is causing.

Memory use as seen in Process Hacker goes as high as 13 Gb of memory (this PC has 16 gb) before Windows (7, 64 bits) starts complaining that I'm low on memory and must quit some programs. I never have the time to actually do this because MBM is continuing to increase its craziness in the background and the PC blackscreens and I have to hard-reset.

I am having to type this in Notepad over several reboots + kills of the mbam service. It takes less than 8 minutes to end up in the same place with low system memory.

I have disabled self-protection in order to turn the service off via the services console (services.msc) but it refuses to comply completely, and simply turns itself back on every time, where it repeats the cycle of quickly consuming all available RAM.

I have disabled EVERY scan option, notification, check for updates etc. and yet memory usage continues to increase. In the time it took to type this message, it has gone up to 6gb so I'm killing it again.
I am somewhat a fast typist, by the way.

This obviously makes the computer unusable since I can't be expected to restart a ¦²¬²³¦ service every 6 minutes... I don't even think I have time enough between startup and it going insane to run the tools you've suggested to another user here.

Oh, and less important but also relevant, CPU usage sits at a constant 25% even though nothing is happening. No scan; nothing.

I am going to have to uninstall the program to use the PC at all, so please help fix this, quickly...!

 

Here's the progression in Process Hacker:

A few minutes later (meaning about 4, look at the Total CPU time)

And then antother 1-2 minutes (and I just had to kill the service again while typing this)

Keeps going

And this is what I get when I try to kill the service, it does kill the process but immediately restarts it despite my having set Startup to Manual and Service to Disabled...

Same here, I thought it was a hardware issue at first until I found this thread. MWB was running wild processes all over the place prompting me that real time protection was turned off (apparently it did so by itself).

Only solution for me was to forcibly uninstall MWB through Revo Uninstaller, as I couldn't even uninstall it directly.

A shame that a program meant to protect you starts running wild with your PC. I'm a premium user, so hopefully they get this fixed soon. Always been happy with Malwarebytes, but this is a big fail here.

I created an account just to respond here. The same thing happened to me and it started today 01/27. I've spent about 3 hours on it thinking I got infected somehow.

I've done MBAM uninstall, reboot, restore points, re-install, reregister premium and have been at this crap for hours.

The second malwarebytes updated the malware bytes service in proccesses (Win 10) is literally expanding memory until all of memory is gone, 16GB of gaming memory, and both monitors go black and then windows beeps and I can't do jack except reboot.

For now ending the task on malwarebytes service fixes it but now I have no protection.

 

PLEASE SUPPORT STAFF NO CANNED RESPONSES. Also, web protection is off.

After a clean install, I'm running the latest download and everything was working so I updated the software itself in the mbam tray and then it started going crazy again!

Oh and I can guarantee you there are way more people having the issue then reporting it here. Don't you guys test these updates out first in a beta environment?

I'm going to install the version I downloaded and not update it and make sure it's ok.

Version right now is 3.3.1.2183.. about to uninstall and install the one I downloaded this morning after all this began -_-

 

P.S. guys this is called a memory leak and is the result of some code being out of place..

I am experiencing the same issue. If I had to guess I think your product has been compromised via DDoS via internal resources. I would suggest fixing this immediately. I have been a loyal customer for over 3 years now, and you risk losing a customer. From the posts I have seen here on your forum site,  just today I think I won't be the only customer you lose! ;--)

Same problem.

  • Nothing wrong last night, came downstairs to a crashed PC.
  • Rebooted, system seemed fine.
  • Then slowdown started and Malwarebytes web protection turned off.
  • System started running slow and janky, opened task manager.
  • Malwarebytes was using 62% of system RAM and 28% of CPU. RAM usage was climbing by the second.
  • Malware bytes ran my system out of available memory, system crashed.
  • Rebooted, same issue: RAM usage climbs until system crashes.
  • Quitting Malwarebytes completely resolves the issue.

I am running an Intel Core i7-6770HQ processor (2.6 GHz) and 16GB of DDR4 RAM, with the OS and data on an M.2 SSD. Clean install of Win10 when I built the system two months ago.

It's not a problem with my system, it's a problem with Malwarebytes.
