What is LicenseError?

The Malwarebytes research team has determined that LicenseError is a Tech Support Scam. These so-called "Tech Support Scammers" try to trick you into calling their phone number for various reasons, all of which turn out to be fraudulent in the end.
For more information on this particular type of Windows Shell hijackers please read this blogpost.

How did LicenseError get on my computer?

Tech Support Scammers use different methods for distributing themselves.
This one makes it appear the system hangs after logging in, while displaying the Tech Support Scammers number.



How do I remove LicenseError?

Our program Malwarebytes Anti-Malware can detect and remove this potentially unwanted application.
But due to the way this TechSupportScam installs itself we will need a way to bypass it.
If you already have Malwarebytes Anti-Malware installed, you can use Chameleon to get rid of this infection.

• In the TechSupportScam screen use the keycombination Ctrl-Alt-Del.
• From the resulting list of options choose "Start Task Manager".
• In the list of processes find every process called "error(.exe)", select them one by one and click on the "End Process" button. Confirm that you want to end the process.
  
• Then in the Taskmanager menu click "File" > "New Task (Run...)" > "Browse..."
• In the resulting explorer window navigate to the Chameleon folder, usually "C:\Program Files (x86)\Malwarebytes Anti-Malware\Chameleon\Windows" and doubleclick on "iexplore(.exe)".
• and follow the instructions ("Press any key to continue"). Chameleon will kill the process and start Malwarebytes Anti-Malware to finish it up.
  
• Reboot when prompted to do so and everything should be fine.

If you do not have Malwarebytes Anti-Malware installed, please proceed as follows.

• In the TechSupportScam screen use the keycombination Ctrl-Alt-Del.
• From the resulting list of options choose "Start Task Manager".
• In the list of processes find every process called "error(.exe)", select them one by one and click on the "End Process" button. Confirm that you want to end the process.
  
• Then in the Taskmanager menu click "File" > "New Task (Run...)" and type "explorer" and then press "Enter".
• You should see your Desktop again. If not, navigate to "C:\Program Files (x86)" and find a folder that has the same name as your computer. In that folder find the file "error(.exe)" and delete the file. Reboot when it is gone and your system should boot normal again.
• Next, download Malwarebytes Anti-Malware to your desktop.
• Double-click mbam-setup-version.exe and follow the prompts to install the program.
• At the end, be sure a check-mark is placed next to the following:
  • Enable free trial of Malwarebytes Anti-Malware Premium
  • Launch Malwarebytes Anti-Malware
• Then click Finish.
• If an update is found, you will be prompted to download and install the latest version.
• Once the program has loaded, select Scan Now. Or select the Threat Scan from the Scan menu.
• 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 LicenseError?

• No, Malwarebytes' Anti-Malware removes LicenseError completely.
