What is Troubleshooter?

The Malwarebytes research team has determined that Troubleshooter is a Tech Support Scam.
This one tries to get you to send $25 to their PayPal account.

How do I know if my computer is affected by Troubleshooter?

You will see these screens shortly after the file is executed:

Clicking Next on the second one gets you this screen:

and this one if you follow through:

and this one when you try to close your computer after Ctrl-Alt-Del:

How did Troubleshooter get on my computer?

Tech Support Scammers use different methods for distributing themselves. This particular one was offered as a cracked software installer.

How do I remove Troubleshooter?
Our program Malwarebytes Anti-Malware can detect and remove this potentially unwanted application, but due to the nature of the infection this will require a few extra steps.
  • Reboot your computer into "Safe Mode".
  • You will see a black screen with Safe Mode in the corners. Use the Ctrl-Alt-Del keys and Start Task Manager from the resulting screen.
  • In the Windows Task manager click File > New Task (Run...). In the prompt type %temp% and click OK.
  • This will open the Temp folder. In that folder find the folder csrvc. In that folder delete the file Troubleshoot.exe
  • Then go back to the Windows Task manager and click File > New Task (Run...). In the prompt type services.msc and click OK.
  • In the list of services find the one called csrvc
    service.png
    and rightclick on it. In the poperties screen set the "Startup type" to Disabled.
  • Then use Ctrl-Alt-Del again and Reboot the computer from the resulting screen.
  • After the reboot use the Ctrl-Alt-Del buttons again to Start Task Manager from the resulting screen.
  • Then go back to the Windows Task manager and click File > New Task (Run...). In the prompt type explorer and click OK.
  • You should now have access to your Desktop again.
  • Then continue with the instructions below.
  • Please download Malwarebytes to your desktop.
  • Double-click mb3-setup-consumer-{version}.exe and follow the prompts to install the program.
  • Then click Finish.
  • Once the program has fully updated, select Scan Now on the Dashboard. Or select the Threat Scan from the Scan menu.
  • If another update of the definitions is available, it will be implemented before the rest of the scanning procedure.
  • When the scan is complete, make sure that all Threats are selected, and click Remove Selected.
  • Restart your computer when prompted to do so.
Is there anything else I need to do to get rid of Troubleshooter?
  • No, Malwarebytes removes Troubleshooter completely.
  • You can uninstall adwizz from the list of installed Programs and Features
  • You may still see this message when you reboot:
    warning5.png
    If this is true, and you want to remove it, follow the instructions in the reply to this post.
How would the full version of Malwarebytes help protect me?

We hope our application and this guide have helped you eradicate this hijacker.

As you can see below the full version of Malwarebytes would have protected you against the Tech Support Scam.

erunt.png Backing up Registry with ERUNT

Modifying the registry may create unforeseen results, so we always recommend creating a backup prior to doing that!

Please download ERUNT and save the file to the desktop.
  • Install ERUNT by following the prompts, but say No to the portion that asks you to add ERUNT to the startup folder.
  • Right-click on the erunt.png icon and select RunAsAdmin.jpg Run as Administrator to start the tool.
  • Leave the default location (C:\WINDOWS\ERDNT) as a place for your backup.
  • Make sure that System registry and Current user registry are ticked.
  • The third option Other open users registries is optional.
  • Press OK to backup and then press YES to create the folder.
This tool won't generate any report.
You can uninstall it after you are done with the cleaning.

reg_file_icon.jpgRegistry Fix

We need to prepare a fix file first.
  • Press the WindowsKey.png + R on your keyboard at the same time.
  • A Run window should appear in the lower left corner. Type in notepad.exe and press Enter.
  • In the shown window paste in the following script. Make sure that all of the code box content is pasted!
    Windows Registry Editor Version 5.00
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
    "legalnoticecaption"=-
    "legalnoticetext"=-
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
    "LegalNoticeCaption"=-
    "LegalNoticeText"=-
  • Go to File menu and select Save as.
  • Make sure that the Save as type option is set to All Files (*.*) and the place to save will be your desktop.
  • Name the file fix.reg and select Save.
  • After that, your prepared fix.reg file should be located on your desktop.

    Now we need to import the file into the registry.
    • Locate the fix.reg file on your desktop.
    • Right-click the reg_file_icon.jpg icon of your file and select Merge.
    • You'll be prompted about adding the information to the registry. Please agree.
    After this please manually reboot your machine.
