How do I remove TSS GMusicPlayer?
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.
  • Note that the password for the prompt is web01com36, but it might require several tries.
  • Once you succeed, the text field of the prompt will be greyed out, at that point you can use Ctr-Alt-Del to access Taskmanager.
  • End the processes called active.exe, doctormypce.exe, and tt.exe. Then use Taskmanager to Run explorer.
  • Leave Taskmanager open as you will have to end the processes called jj.exe and mycent.exe.
  • 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 TSS GMusicPlayer?
