Need Help, AgentMonitor??

My iMac every time I restart it a message comes up saying "the application AgentMonitor quit unexpectedly" and I can click "ignore" "restart" or "report to apple"

I've never heard of this app and it's not in my applications folder. Is this some kind of spyware running in the background? I didn't think that could happen on a mac.

Does anyone have any thoughts as to what this is or how I can get it off my iMac?

Thanks.
