I have the same issue, with the GoToMeeting still sending multiple and continuous background items to be updated despite it mannually being uninstalled. The application, despite being uninstalled, also remains in the setting folder for applications that are allowed to perform background functions. I have removed the permission from GoToMeeting from being able to run in the background, but it continues to run in the background. (I also removed permission when it was installed but that did not stop the background updates either.) An application that can defeat MAC systems and runaround primary security functions would seem to be something Apple would assign a high priority. God only knows what nefarious parties have learned to hack into people's computers using GoToMeeting's strategey not to allow users to uninstall its app and have it manipulate the computer in the background.
Specific questions:
I am entirely new to code-type activity (one of the reasons I love my MAC). I found my way to the terminal and added the first line of text, which returned: "LaunchAgents %"
When I used "Is" on the next line, it returned: "command not found."
I am sure it's simple. I appreciate your kind assistance in helping the noncoding MAC user figure out how to remove nefarious software that somehow got past the MAC security police.
