The genuine TeamViewer_Service.exe file is a software component of Teamviewer Service by Teamviewer.
The TeamViewer service enables a secure remote desktop access and is running in the background. It allows incoming connections even though no User is logged on. You can stop this service: Run "services.msc" and go find the Teamviewer service. Then open it up and set it to "manual", that way the service will only launch when you launch Teamviewer. You can then stop the service so it isn't running at that moment.
