Windows Updates Wiped Malwarebytes Off My PC

[rlbafosam]

Today windows installed 3 updates. When it was done, Malwarebytes was completely wiped from my machine!

I understand I can re-install, but I hope someone is paying attention.

I also posted a question on the removal of MWB. I thought it was a virus but now based on your post it may have been a windows 10 update.

Hope this does not indicate Microsoft is trying to delete any non Microsoft software.

I got the 2017-10 Cumulative update today also. My Malwarebytes is there and running after installing the Windows update. Don't know if this helps, but I hope so.

I got the KB4041676 update last night, although my malwarebytes was fine. I upgraded my windows at around midnight, but earlier in the day yesterday i got an update for malwarebytes, and ever since then, custom full scans with rootkit enabled is taking 1hr+ and it gets stuck on one file. Before these updates, it would take 30 or so minutes for this type of scan. i assume these updates just messed some stuff up, which really sucks.

@rlbafosam we've seen a few people report this, but we haven't been able to reproduce it yet. Do you have any other AV software on your machine?

Mine's gone too

Same problem here.  Malwarebytes just disappeared after the Windows update.  I also have Norton running but never a problem with Malwarebytes.

Same here.

1. Download the latest MB 3 installer from : https://downloads.malwarebytes.org/file/mb3
   2. Run the installer on top of your existing product. (Note you don't have to uninstall anything, just run the installer again)

Can you please grab your windows update logs? To do this, perform the following:

1. Navigate to C:\Windows\Logs
2. Right click on WindowsUpdate and choose Send to -> Compressed (Zipped) folder
3. This should prompt you to create the file on your desktop
4. Once the zip is created on your desktop, please upload it here or private message it to me

Apparently Microsoft's major updates will remove any application Microsoft thinks will be a conflict with their software. Various other forums have reported this problem. "All of your files are exactly where you left them” screen will appear like normal–this screen always appears during major updates–but Windows will actually have removed some of your program files.

To me this is something that should be disclosed by MS who seems to know which programs will be in conflict. Not good.

I had CCleaner and Malwarebytes removed. My guess is MS will not even acknowledge this problem.

I agree about disclosure by MS.  At minimum a notification at the time of the update.

CCleaner was not removed from my PC with the Windows update.
