What is AG Music Player?

The Malwarebytes research team has determined that AG Music Player 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.

How do I know if my computer is affected by AG Music Player?

You will see this screen as soon as the executable is run:

and this browser window to a site that has been removed:

After the reboot you will be confronted with these screens:

How did AG Music Player get on my computer?

Tech Support Scammers use different methods for distributing themselves. This particular one was offered as an installer for a music player.

How do I remove AG Music Player?

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.
We will describe two possible methods of removal. The easiest one if you have more than one user-account is to:

Method 1
  • Use the key combination Ctrl-Alt-Del and from the resulting menu choose "Switch User".
  • Log into another account that is not affected and delete the folder "C:\Program Files (x86)\AG Music Player". You will need Adminstrator rights.
  • Reboot the computer despite the still active user.
  • Of course you can use any other means to remove named folder that you are comfortable with, like "Safe Mode with Command prompt" or bootable media. In "Safe Mode with Networking the lockscreen will still be active.
Method 2
  • When confronted with the lockscreen shown above, use the key combination Ctrl-Alt-Del
  • Use the password "6257DCBBF787DFE4" in the "Windows Activation Error!" prompt.
  • You may have to try this a few times.
  • If the password has been accepted the prompt will change and look like this:

    the textfield is no longer accessible.
  • Now use the key combination Ctrl-Alt-Del.
  • From the menu choose "Task Manager".
  • In Taskmanager select the process called "R.exe" with the description "R.exe".

  • Click on "End Process" to stop the screenlocker.
  • Repeat that procedure for the process "fatalerror.exe" with the description "Microsoft .NET Framework".
  • Then in Windows Task Manager click File > New Task (Run...) and type "explorer" in the prompt. Click OK to run explorer.
  • Now you should see your desktop, but the Tech Support Scammers prompt will be back.
  • Use the password "6257dcbbf787dfe4" in the "Windows Activation Error!" prompt.
  • You may have to try this a few times.
  • If the password has been accepted the prompt will change again.
  • Now use the key combination Ctrl-Alt-Del.
  • From the menu choose "Task Manager".
  • Again you will have to end the process "fatalerror.exe" with the description "Microsoft .NET Framework".
After using one of the two methods above continue with the instruction below.
  • Please 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:
    Launch Malwarebytes Anti-Malware
  • Then click Finish.
  • Once the program has loaded, select Scan Now. Or select the Threat Scan from the Scan menu.
  • If an update 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 AG Music Player?
  • No, Malwarebytes' Anti-Malware removes AG Music Player completely.
How would the full version of Malwarebytes Anti-Malware help protect me?
