Intermittent, random, Windows 7 PC freezes/lockups

Recommended Posts

Since 17/12/2018 I started getting intermittent random PC freezes/lockups on my Windows 7 PC. 
I'm a long term user of MB, also on two Windows 10 PCs which are not having any problems.

My MB version on the Windows 7 PC (now uninstalled) were:
Malwarebytes Version: 3.5.1.2711
Component Package Version: 1.0.508
Update Package Version: 1.0.8722
My Windows 7 version is:  Windows 7 Ultimate  Version 6.1 (Build7601: Service Pack 1)

My PC would freeze (screen frozen no mouse, or keyboard action possible) at random intervals, anywhere from 2 minutes after login to 120 minutes after login. 
Failures NEVER occurred in Windows Safe Mode with networking enabled,
nor in Windows normal mode with the Ethernet network disconnected.
Failures DID occur in Windows Normal Mode at a login prompt, without any users logged in or any applications running.

Unaware that  MB was the cause of my freezes, following one of the failures, I detected activity in the log file MBAMSERVICE.LOG as pasted below.
Accessing reports in these Malwarebytes forums I read entries about MB causing freezes earlier in 2018 such as "3.4.4 is freezing my computer"  By Anorax, March 12, 2018 in Malwarebytes 3 Support Forum, so I decided to completely uninstall MB on my Windows 7 PC.

From the time I first logged in to Windows 7 normal mode after Malwarebytes was removed (now some 30 hours) I have  not had any further PC Freezes, or lockups. 

What I am trying to determine is whether others have had similar 'freezing lockups' in Windows 7? 
What version of MB I should be using to prevent them?
And is there any configuration action I can take to prevent such freezes/lockups happening again?

Thank you.

:welcome:

Hello Belsnerd.

Yes, there are some Windows 7 - 64 bits systems that experience freeze-ups.

The current advice is to go back to the version of Malwarebytes that has component update 1.0.482

Our Developers are aware of this issue and continue to work to resolve this. Until that time, please follow the advice in the reply to   your support ticket to switch back to the previous version of Malwarebytes ( with the component 1.0.482 ) .

I will close this thread here.   Please follow the advice & response on your helpdesk case.

Just by the way, there is a pinned topic in this area of the forum about the issue.     

Sincerely
