Hi Beach Boy.
Its possible that the entry is listed under your startup programs and it should be a fairly straightforward process of removing the entry from startup.
Download and run Autoruns from here, Autoruns
Save the folder to your desktop. Right click the folder and click extract all to extract the folder. Once the folder is extracted open the folder. Run the Autoruns.exe program by right clicking on it and selecting Run As Administrator. Once the program opens click the Logon Tab to display all the startup programs that are starting up with your computer.
Highlight the Performersoft LLC entry and delete the entry from the list to remove it from starting up with the computer. Reboot the computer after deleting the item and see if it is no longer starting up with the machine.
