Did the Task Manager really say, "You don't have permission to do that (like a respectable trojan)"
How do you know it is a trojan or other malware?
We could wait and see if your enquiry at the link below gets a response;

But a quick Google search for worker.exe seems to suggest this might be to do with Microsoft Exchange.

Today i noticed background worker.exe process in task manager. When I try to kill the process, it says: You don't have permission to do that (like a respectable trojan). Malware bytes does not recognize it. How can i get rid of it?
