Hello everyone, i just wanted to install MalwareBytes free version for my own PC to see if i have any malitios code using the admin account but after i downloaded the file from the official page i get an note saying that i do not have sufficient permissions to install MB. I tried to modify permissions from the folders in the registry also on the disk but still didn't helped. I also ran the FRSTEnglish.exe tool and got the output from the files attached and my windows defender also blocked some threds called Behavior:Win32/UACBypassExp.ZI and PUA:Win32/Creprote... I hope someone could help me

Thanks for posting in the Malwarebytes for Windows Help forum.

If you are having technical issues with our Windows product, please do the following:

Malwarebytes Support Tool - Advanced Options

This feature is designed for the following reasons:

  • For use when you are on the forums and need to provide logs for assistance
  • For use when you don't need or want to create a ticket with Malwarebytes

How to use the Advanced Options:

  1. Download Malwarebytes Support Tool

  5. The Advanced menu page contains four categories:
    • Gather Logs: Collects troubleshooting information from the computer. As part of this process, Farbar Recovery Scan Tool (FRST) is run to perform a complete diagnosis. The information is saved to a file on the Desktop named mbst-grab-results.zip and can be added as an email attachment or uploaded to a forum post to assist with troubleshooting the issue at hand.
    • Clean: Performs an automated uninstallation of all Malwarebytes products installed to the computer and prompts to install the latest version of Malwarebytes for Windows afterwards. The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.
    •  Repair System: Includes various system-related repairs in case a Windows service is not functioning correctly that Malwarebytes for Windows is dependent on. It is not recommended to use any Repair System options unless instructed by a Malwarebytes Support agent.
    • Anonymously help the community by providing usage and threat statistics: Unchecking this option will prevent Malwarebytes Support Tool from sending anonymous telemetry data on usage of the program.

  11. Click the Yes button to proceed. 
  12. Save all your work and click OK when you are ready to reboot.

Hello @xxxmancs

Error: (12/09/2020 08:59:02 PM) (Source: SecurityCenter) (EventID: 3) (User: )
Description: The Windows Security Center Service was unable to establish event queries with WMI to monitor third party AntiVirus, AntiSpyware and Firewall.


Error 5 from RegOpenKeyExW


Something is blocking access which often is due to an aggressive antivirus, but in this case I'm not seeing an antivirus setup to do that. Not seeing Controlled Folder access kick in either, so something else is going on. It very well could be due to some type of corruption.

Please try the following and post back what you see or what error you get.

Click on START and type in CMD.EXE and when it shows on the menu right-click and select "Run as administrator" then type in the following and press the Enter key.


Then do the following, you can type it but it might be easier to copy and paste it into the command prompt windows.

DISM.exe /Online /Cleanup-Image /ScanHealth

i may did something wrong when i tried to resolve the problem and i may messed up with permissions or something but i also don't have any antivirus besides the one of the windows, i had bitdefender before but it was deleted when i proceeded those scans with your app.

Okay, let's go ahead then and do another scan with another tool and see what it says


Let me have you run a different scanner to double-check. I don't expect it to find anything, but no harm in checking.

I would suggest a free scan with the ESET Online Scanner

Go to https://download.eset.com/com/eset/tools/online_scanner/latest/esetonlinescanner.exe

  • It will start a download of "esetonlinescanner.exe"
  • Save the file to your system, such as the Downloads folder, or else to the Desktop.
  • Go to the saved file, and double click it to get it started. 
  • When presented with the initial ESET options, click on "Computer Scan".
  • Next, when prompted by Windows, allow it to start by clicking Yes 
  • When prompted for scan type, Click on Full scan 
  • Look at & tick  ( select )   the radio selection "Enable ESET to detect and quarantine potentially unwanted applications"   and click on Start scan button.
  • Have patience.  The entire process may take an hour or more. There is an initial update download.
  • There is a progress window display.
  • You should ignore all prompts to get the ESET antivirus software program.   ( e.g.  their standard program).   You do not need to buy or get or install anything else.
  • When the scan is completed, if something was found, it will show a screen with the number of detected items.  If so, click the button marked “View detected results”.
  • Click The blue “Save scan log” to save the log.
  • If something was removed and you know it is a false finding, you may click on the blue ”Restore cleaned files”  ( in blue, at bottom).
  • Press Continue when all done.  You should click to off the offer for “periodic scanning”.
