Malwarebytes Vanished, will not reinstall

[JustBillH]

This has happened before.  I realize Malwarebytes is no longer installed on my laptop, with no indication when or why it was removed.  I try to reinstall and it asks to reboot to continue installation.  Upon reboot, it asks once again to reboot to continue installation ad nauseum.  I think the last time this happened I was able to run mb-clean and get the application installed again.  This time, no go.  I've run it a few times and run ccleaner as well to remove all traces, but each installation attempt leads to the same cycle of reboots.  

Is there anything I can do at this point?

Can you please try this.

1. Open your Registry and check for the following key:  HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Malwarebytes Anti-Malware_is1

2. Delete the whole key.

3. Now install Malwarebytes 3.3.1 https://downloads.malwarebytes.org/file/mb3

Please let me know if that worked.

[JustBillH]

The key did not exist.

Can you please grab the logs mentioned in the thread below

Not a lot to see in the mb-check log anymore because I've pretty much stripped every reference to Malwarebytes that I can find.  And there were a lot - This laptop has been going for years and it has always had malwarebytes on it... originally the free version, then a corporate version, then a home license.  It's gone from Win 7 to Win 10 in place.  It's been through a lot.  LOL

Realized the files should be posted in another part of the forum.

...and I deleted the files thinking they were supposed to be in another forum and just realized I was in the right place to begin with.

Are there any online malware scanning products that I could use to give my system a once over just to make sure there's nothing malicious involved?

[dcollins]

Looks like you still have a trace of 1x left on your system. Can you run mb-clean again, and provide the mb-clean-results.txt file on your desktop?

[JustBillH]

The mb-clean pretty much gives up immediately acting like it can find no trace.  Doesn't even try an install anymore.

Ok, let's see what other keys may be leftover. Can you do the following please?

1. Press Windows Key + R to open the run dialog
2. Type regedit in the window and click Ok
3. In the regedit window, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion
4. Right click the Uninstall key on the left side and choose Export
5. Save the .reg file somewhere on your computer and close Regedit
6. Find the .reg file, right click it and choose Send to -> Compressed (Zipped) folder
7. Upload the zip file

[JustBillH]

Here you go. 

Uninstall.zip

I'm seeing a lot of forum posts similar to mine...

@JustBillH can you download the attached zip file and extract it, then double click the clean.reg file and import it. This should remove a leftover registry entry on your machine that is causing this issue (an old version of MBMC)

clean.reg.zip

SUCCESS!!! Thanks so much for your help.

Yep! Thanks for working with us, we'll be sure to update our support tools to clean up this key that we were missing as well
