removing startup item from com.apple.launchd

I installed a program a few months ago, it had a startup option that I did install. Later, I decided to remove the program, but it seems to have left the startup script or item even after I uninstalled it.... and its trying to start every few seconds.

How can I remove this item?

Here is it from the console

$ com.apple.launchd[1] (com.jft.PdaNetMac[24476]): Exited with exit code: 1
$ com.apple.launchd[1] (com.jft.PdaNetMac): Throttling respawn: Will start in 10 second

Those are indeed the standard locations that launchd looks in. Make sure to check the locations of your home directory as well as the ones of the root.

If you can't find the file, you can also try the following in the Terminal:

$ launchctl remove com.jft.PdaNetMac

To see a list of all launchd jobs:

$ launchctl list
PID Status  Label
78960   -   0x7fe25c1052f0.anonymous.launchctl

For more information, try man launchd and man launchctl.

Check the following locations ~/Library/LaunchDaemons, ~/Library/LaunchAgents ,/Library/LaunchDaemons,/Library/LaunchAgents/,/System/Library/LaunchDaemons/, and /System/Library/LaunchAgents more then likely there will be a file named com.jft.PdaNetMac within one of those directories. Simply move it to the trash and restart.
