Instead of updating, Malwarebytes Just deleted itself

[TheBox]

I got a notice to download a new version this morning and have had the same results.

 

I've been able to install a later version, 3.0.4 I believe, but the web protection is stuck on starting for that and the scans stop after 3-5 seconds.

 

When I've tried to install the latest version, from the Malwarebytes website, I have the same thing happen as well. It looks as if it's going to install, then pops up a window saying it needs to reboot. Once that's done, it's removed any version that's on the computer and has left a txt file on the desktop with the mb license key in it. Once rebooted, it goes into a cycle of trying to install and then telling you it needs to reboot. All the while not installing anything.

 

Any help with this issue would be greatly appreciated.

I had the same thing happen. When I go to install the version in the link, it just goes into a cycle of acting like it's stalling and then tells you it needs to reboot. Once rebooted, it acts like it's going to install and they tells you to reboot again.

 

When it tells you to reboot, it totally removes the program and leaves a txt file on the desktop that had the license key in it.

 

Please advise

Hello @TheBox

So basically everytime you run the installer you asked for a reboot and the installation never completes?

Is that correct?

[TheBox]

Yes, that is correct

[TheBox]

I've gone as far as doing an mbam clean as well and still same results. Even though I am the admin of my computer, I've also tried running it normally and right clicking and running as admin.

[nikhils]

Just on a hunch do you have this following key in the registry?

HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{0F50E3D9-711C-42AD-AFAB-1EA5AB439978}

Just thought I'd throw my 2 cents in and let you know that I'm basically having the same issues as of this morning.

 

I have full admin rights, have also done an mbam clean and same result. It also removes the program and leaves a txt file on the desktop with the license key when it asks you to reboot.

 

Thank you

[TheBox]

I don't see it

[nikhils]

Can you download the latest mb-clean build from https://downloads.malwarebytes.com/file/mb_clean and run the same.

After mb-clean runs, go  ahead and reboot your machine.

Then try installing the latest 3.2.2 product.

Let us know if that works.

@TheBox

Try this first. Restart the computer and do the following.

Just download the latest installer from : https://downloads.malwarebytes.org/file/mb3

Run the installer

That is the same file that I've downloaded 5 different times now. As previously stated, doing a reboot doesn't nothing. Even after everything has been wiped clean from the machine, it will still not load and goes into the reboot loop.

 

[TheBox]

Same results. It deleted the mb-clean.txt that was on the desktop as well when this came up.

[nikhils]

Got it. Can you please do this:

Follow the forum post below and please post the mb-check-results.zip file after running FRST and mb-check.

Thank you.

[TheBox]

Here it is

I have merged all of your topics together. We don't need three separate topics to troubleshoot this issue. @nikhils is working on your issue and will respond with more details

[nikhils]

Can you please go to : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ and please delete the following 2 keys:

{3B88B200-D13F-4F51-B9EC-1D98DBF9ABD4}) (Version: 1.60.2 - Malwarebytes Corporation)
{FBC350D5-10D0-4B9B-A9AC-5F2EA07770D5}) (Version: 1.60.2 - Malwarebytes Corporation)

After deleting the 2 keys can you please try running the installer again?

Thank you.

[TheBox]

The 2nd one, FBC350D5-10D0-4B9B-A9AC-5F2EA07770D5, was the only one found and I deleted it.

 

Ran the installer again and it's still the same message as before.

[nikhils]

Can you also please check the HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\ hive and make sure there are no Malwarebytes keys living there. If you find any just delete the key and try reinstalling the 3.2.2 product.

[TheBox]

I'm sorry. For some reason when I searched the first, 3B88B200-D13F-4F51-B9EC-1D98DBF9ABD4, it searched in the Wow6432Node. I repathed it and found the other one you mentioned. I got it deleted and was able to install 3.2.2

 

Thank you for all of your help. It is greatly appreciated. Why did this happen to begin with?

[nikhils]

That's great to hear. The most probable cause was you had an older Corporate version of MBAM 1.x installed which could not be uninstalled cleanly.

The MB 3.2.2 has a few additional checks and blocks in place. It would have detected the presence of an older product via the registry keys and would have blocked the install.

Thank you.

[TheBox]

Good to know.

 

Thank you again for all of your help and quick responses!

 

Have a good one!

[nikhils]

Very Welcome. Stay safe online.
