Hello there, I've tried removal tool and running it through service.msc (it won't start - error 1053) as well as reinstalling and it still won't run. I've attached logs, sorry for the Polish language in logs, I can switch my system language to English if it's any hassle for you.

Regards,

Greetings,

It appears that you have a component of User Account Control disabled.  This may be the cause of the problem because Malwarebytes, just like most other modern software, has been designed to work with User Account Control active which means that having it disabled could cause the program not to have the appropriate permissions it needs to perform its actions and this also extends to the installer so first, I would suggest changing User Account Control back to default (more info on the various UAC settings and what they do can be found here):

UAC Settings

==================================
EnableLUA:            On
Consent Prompt Behavior Admin:    Off

Once that is done, restart the system and then try to do the following to perform a clean installation again and hopefully it will work properly this time:

1. Download and run the Malwarebytes Support Tool
2. Accept the EULA and click Advanced Options on the main page (not Get Started)
3. Click the Clean button, and allow it to restart your system and then reinstall Malwarebytes, either by allowing the tool to do so when it offers to on restart, or by downloading and installing the latest version from here
   

If that did not resolve the issue, then please try temporarily disabling Avast to see if it is then able to install and run properly, and if it is, create exclusions in Avast for the items listed on this page.

If the problem still continues, then it could be an infection causing the problem so I would suggest trying to run the special build of Malwarebytes Anti-Rootkit found in this topic and removing any threats it detects, then restarting your system to complete the threat removal process if it prompts you to do so.  If that did not resolve the problem, then please try running ADWCleaner to have it scan your system, and likewise have it remove anything it detects and then restart to complete the removal process if prompted to do so.  After that, try installing Malwarebytes again by downloading the latest version from here to see if it now works properly.

If the issue still isn't resolved then please try installing Malwarebytes in Safe Mode with Networking by running the installer you downloaded in the last step above.  If it is able to install and run in Safe Mode, then restart your system and allow it to boot normally then check to see if it is now functioning properly.

Please let us know how it goes and if the issue still persists.

Thanks
