There is a running process called "RelayUploader" on a Mac machine. The user associated with that process is "nobody". What is the purpose of this process? Is it something legit or should this process be a security concern?
This isn't a proper answer, just some things you may want to try:
RelayUploader (aka Relay.Uploader) seems to be associated with a company called TechSmith... do you have any of their apps?
If you have a malware of virus scanner, you should run a scan on it.
Have you looked at the
Activity Monitor? (If not, open
Activity Monitor, select the process from the list, then click the
iicon in the Activity Monitor dialog). What does it say in the
Open Files and Portstab? Do you recognize any of these files?
