MB 3.7.1 crashes on start

[Gagome]

Hello,

I got prompted to update to MB 3.7.1. After the installation completed successfully I didn't see the MB icon in the notification area.
I am running Windows 10 Pro 1803 x64.
I checked Event Viewer and found:
 

Faulting application name: mbamservice.exe, version: 3.2.0.765, time stamp: 0x5c508d96
Faulting module name: MwacLib.dll, version: 3.1.0.535, time stamp: 0x5c4b9e72
Exception code: 0xc0000005
Fault offset: 0x000000000000d95c
Faulting process id: 0x2a10
Faulting application start time: 0x01d4c546b98e792a
Faulting application path: C:\Program Files\Malwarebytes\Anti-Malware\mbamservice.exe
Faulting module path: C:\PROGRAM FILES\MALWAREBYTES\ANTI-MALWARE\MwacLib.dll
Report Id: d6317523-d568-4827-a747-06c3d1de023c
Faulting package full name: 
Faulting package-relative application ID: 

Then I downloaded mb-support-1.3.1.553.exe and did run it.
It tried to repair MB. I had to do a reboot too. But after my PC started I found the same messages in Event Viewer.
I collected all log data.
You will find all attached.

I have now the same problem on my second device which is too Win10 Pro 1803 x64.

Maybe there is a bug in MB 3.7.1?
Can you please look into this?

Thanks.

Hello,

The source of the issue is with the ProxyCap program you have installed (due to the insertion of a third-party DLL file into the Winsock).

We are currently investigating the issue. In the meantime, you will either need to uninstall ProxyCap or revert to the previous installer version of Malwarebytes (3.6.1).

[Gagome]

Hello,

ProxyCap is needed and I will not uninstall it.

I hope you find a solution.

From where can I download the previous installer of MB 3.6.1?

Thanks.

[LiquidTension]

Hello,

Here is a download link to version 3.6.1: https://malwarebytes.box.com/s/plo5hdm39who0lwld7j1y5e55rum8z33

[Gagome]

I have installed version 3.6.1 but now I get several times during a day a prompt to upgrade to a new version.

But I have set in Malwarebytes Settings Application Updates to Off.

Why do I get the prompt then?

This is really getting to be annoying.

What can I do to avoid those prompts?

I guess this is a bug in version 3.6.1.

True, I hope you can fix the problem in 3.7.1 to make it work together with ProxyCap. But currently getting the prompts several times during a day is really annoying.

Sure, you need to disable (OFF) the two items Under Settings -> Application -> Application Updates

If the program has already downloaded the update, its pending the install, in order to stop that you need to delete the installer that was downloaded. You may have to disable self protection to delete the file. It is located in the folder:

C:\ProgramData\Malwarebytes\MBAMService\instlrupdate

Hi Gagome,

As Porthos mentioned above, you will need to delete the downloaded installer file. Here are steps on how to do so.

• Open Malwarebytes. Click Settings followed by Protection.
• Scroll down to Startup Options and turn the, "Enable self-protection module" setting off.
• Press the Windows Key + R on your keyboard at the same time.
• Type %programdata%\Malwarebytes\MBAMService and click OK.
• Right-click the instlrupdate folder and click Delete.
• Reverse the earlier change made to the Self-Protection setting.
   

Thank you for providing feedback on the full version update process/behaviour. We believe it's paramount for updates and upgrades to be more transparent in the future.

[Gagome]

Hello Porthos & LiquidTension,

Yes, I have already followed the advice from Porthos and I have deleted the downloaded new installer.

And now I no longer get the prompts to install the new version.

I just wanted to wait a day to find out if it really is working before I provide feedback.

 

The now open question is: are you able to fix the issue with ProxyCap?

We are actively investigating the issue. As soon as we have an update, I'll respond back to this topic.

Does MB 3.8.3 solve this problem?

[exile360]

Yes, it should resolve this issue as there were many bugfixes for conflicts and issues involving the Web Protection component, however please let us know if you are still seeing any issues after installing it and enabling Web Protection.

Thanks
