MB crashes on XP (after update XP with new POS updates)

Recommended Posts

I keep my XP machine updated with the POS hack.  So the problem I just started having with MB on my XP machine is the same problem anyone would have on an XP POS machine.

Today, after updating with KB4056564-V2, KB4089453-V2, KB4095516, KB4095528, KB4103768, KB4101477, KB4130957, KB4131188 and KB4134651, MalwareBytes just crashed.  UNinstalling with MB-clean and REinstalling various versions of MB did not work - all crashed.

Any ideas?  Thanks.

Sorry, but mb-support also crashes!!

The Windows Dr. Watson crash reports say this:

EventType : clr20r3     P1 : mb-support.exe     P2 :     P3 : 5ad8d87d
P4 : presentationcore     P5 :     P6 : 590b1abf     P7 : 46a0     
P8 : 47     P9 : system.io.fileformatexception    

Unfortunately, I cannot copy the .dmp or following crash log.

Your program left FRSTEnglish.exe on my Desktop.  What do I do with it?

Can you provide the logs above?

Do note that Malwarebytes does not support XP POS, including regular editions of XP that apply the POS hack. Malwarebytes is not tested against those updates and classifies an operating system with those updates installed as an unsupported operating system. That being said, we can certainly take a look.


Just saw your message, can you try standalone mb-check from https://downloads.malwarebytes.com/file/mb3_check

dcollins - please be sure you install all nine in my list.

If any is missing from your own Microsoft Update list, please see both




However, KB4134651 is needed protection against an exploit that is being seen now!  Please also see < THIS ARSTECHINCA ARTICLE > .

Please fix MB to work with KB4134651 and my other eight updates.

dcollins - I UNinstalled KB4134651, and MB is now working.  No crash on its installation.  Haven't scanned yet, but I'm sure it will be OK.

But we need to install update KB4134651 to protect against a genuine threat that's been seen in the wild.  Please work with Microsoft so that MB works even with KB4134651.

And please let us know.  Thanks.

dcollins - when I tried to run MB, they were Dr Watson-style crashes, not BSODs.  Said that both MB tray and regular MB had crashed.  Unfortunately, I could not copy the TEMP txt files generated by Dr Watson.

Removing that update KB4134651 just now definitely stopped the crashes, as the MSFM expert heinoganda predicted in that last post.

dcollins - and thanks for your fast attention.

Unfortunately, KB4134651 is important - it stops a real threat, not just a theoretical one.  Can you find the solution fast so we can install KB4134651 ?

I am working to find out the cause, but it's doubtful this will be a fast solution since we just had a release earlier this week. On top of that, as I mentioned, this is technically an unsupported operating system so it may not get fixed at all. Once I find out the details, I'll be sure to provide as much information as I can.

I've got a similar (likely identical) crash of MB tray and regular MB on XP after updating . Summary Error signature :    AppName: mbam.exe     AppVer:     ModName: qt5core.dll      ModVer:     Offset: 001aa816.

Any idea if a fix will be likely ?
