Malwarebytes suddenly triggers UAC at every reboot

[DanZ]

I have two life-time licenses (both Win 10).  I've had them installed on the same two machines for several years.  About 2 weeks ago, my laptop started prompting me for my admin password on every boot.  The UAC screen says that Malwarebytes is attempting to modify my system.  I don't think I've changed any Malwarebytes settings in the last several months.  I have both of my systems set to auto login to a user (not admin) account without a password.  Only the laptop is forcing me to enter my admin password at every boot.

How can I fix my laptop so that it can complete the boot process without a UAC prompt for an admin PW?

Please try the following clean removal and reinstall. Make sure you do the install with an account that has Admin rights.

Please uninstall your current version of MBAM and reinstall the latest version using the following guide. MBAM Clean Removal Process 2x

Thanks

That worked - thanks!

[AdvancedSetup]

Great, glad that fixed it. If you need anything else please let us know.

Take care and stay safe out there. Don't forget about frequent data backups.

Malwarebytes appears to be crippling some of my left and right click options, so I've left it uninstalled/cleaned.

---------------------------

Unfortunately, I seem to have a new problem.  Some mouse-click options no longer work on my Thinkpad T410 laptop.  I'm pretty sure that this is not a hardware/driver problem, because left and right clicks work properly on most icons and within programs like Notepad++.

Other than possible silent background updates, I don't think I have added any software to my Thinkpad within the last several weeks other than reinstalling Malwarebytes 2.x Premium.

Left clicking  on the Windows 10 icon in the bottom left of the screen does not do anything.  Right-clicking on the File Explorer icon I have in the bar at the bottom of my screen does not do anything.  Hovering over the highlighted notifications icon indicates I have new notifications, but left clicking on the icon does nothing.  Right clicking on the Notification icon presents a menu which includes: "Open action center", but left-clicking on that does nothing.  The behavior of both my User and Admin IDs are identical.  A week or so ago, they worked fine, just like my desk side computer (with Win 10 and Malwarebytes 2.x Premium) still does.

I did a full Thread Scan this morning without any detected problems.

Unfortunately, I have lots of software installed on my Thinkpad, and a clean install would be very painful.  

It seems unlikely to me, that the reinstall of Macrium Reflect 2.x Premium on my Thinkpad is the cause of my problems.   But I'm pretty sure it is the last "system" level change that I made.  I'm not sure how to proceed.  Do you have any recommendations?

----------------

After I wrote the above, I decided to try one more thing that was easy to recover from.  I deactivated and Cleaned Malwarebytes from my system and now all all of my left and right clicks perform as expected.  I used the following software to try and fix being prompted for my admin password at every boot:

mbam-clean-2.2.2.7

and then mbam-setup-2.2.1.1043

I used the same clean program, which restored normal Windows behaviour.

Can you help me?  How should I proceed.

Malwarebytes is currently deactivated and uninstalled/cleaned from my Thinkpad.

In retrospect, this is probably a new topic.  You're instructions to enable me to reboot without having to enter my admin ID did work.  Unfortunately, I am left with something that is different but just as bad.  My point is, if you have the ability to move this to a separate topic, that would seem best to me.  But if it's a hassle, I'm fine with continuing in this thread.

Hi, @DanZ

In order to provide a bit more system information while you wait for @AdvancedSetup to return, I suggest that you please follow the steps here: Diagnostic Logs.

Then, please ATTACH all 3 logs as "*.TXT" files to your next reply here in this thread.

@AdvancedSetup will review them and advise you further.

Please be patient, as it is a 3-day holiday weekend.
He will return to help you as soon as he can.

Thanks,

[DanZ]

I can wait until he/she comes back - no problem.

I do have 2 question however.  

1. The link you pointed me only tells how to create two logs, not three.  Is there another one that I should create, and if so, how?

2. I removed Malwarebytes from my computer because it appeared to be consistently interferring with some keystroke conbinations, as described above.  Do you want me to reinstall it before I run mbam-check?

Thanks,

Dan

Hi:

There are 2 steps -- for Logset #1 and Logset #2 -- in that pinned topic. 

FRST will generate 2 logs: FRST.txt and Addition.txt -- those will be logset #1.

mbam-check will generate 1 additional log -- CheckResults.txt -- that will be logset #2.

The 3 logs are: FRST.txt, Addition.txt (from FRST) and CheckResults.txt (from mbam-check).

Having said that, as you point out, if you have uninstalled MBAM from your computer, then there is not much point in running mbam-check at this time.

So it's up to you whether or not to reinstall MBAM and then run mbam-check.
The 2 logs from the FRST tool will be a good start.

@AdvancedSetup will advise you further, once he has reviewed those.

Thank you again,

 

[DanZ]

Ah, sorry, I skimmed it and forgot about the two parts.  I'll post the logs tonight and wait for AdvancedSetup to guide me on the next steps.

Thank You,

Dan

I currently have Malwarebytes 2.x Premium uninstalled (and mbam-cleaned).  Attached are the Farbar logs:

Do you have another account on the system that you can log into and test this further. Generally speaking I think there may be something up with the system. I've not heard of any mouse click option issues caused by MBAM before. A new clean user profile might help eliminate or confirm the issue is not user related but system related.

 

[DanZ]

I do not currently have another account, but I can certainly create one.  User or Admin account?

[DanZ]

I created another user-level account on my Thinkpad T410 running Window 10, installed, activated, and updated Malwarebytes Premium and don't seem to have any of the odd click artifacts I had before.  So my inclination is to just leave it installed on that ID.  Other than using a little more disk space, is their any significant downside to that?

[AdvancedSetup]

That would indicate that something is broken on your profile. If it were my computer I would create a new profile with Admin rights and migrate my data over to that profile. If you're using the paid product with real-time protection modules then make sure the other account has Admin rights when you install it and setup scheduled tasks for updates and it should be okay for the most part

 

[DanZ]

OK,

I've decided to leave it as is.  Everything seems to be working fine and there doesn't seem to be any explicit downside.

Thanks!

Dan
