I was having a problem with my fan running all the time. I went to the Finder, Go, Utilities and started the activity monitor. It turned out the Vshieldscanmanager was eating up 100% of the CPU. I called Mcaffee which is now owned by Intel and got tech support. They told me that if I skip autoupdates, the software builds lots of logs and these are accessed overtime the update function tries to decide whether it needs to update or not. So Mcaffee tries to keep scanning looking for update continuity. It slows everything down and completely uses all the CPU it can. Solution: Get with a tech support rep and they will walk you through the uninstall process and indicate where all the hidden files are located then direct you to reinstall the software.
I did and no fan since reinstall.
I had tried the printer solution where a hung job in a printer that is unconnected of off, will constantly try to access the network but even if that is the case and you have Mcaffee installed, and your fan is running, you need to COMPLETELY uninstall Mcaffee and reinstall.
