My MacBook started to run hot and i saw that my printer was taking up 94% of the CPU. Something was trying to print. But since i didn't have my printer connected, it did work. The thing is I didn't ask it to print anything!! So, I force quit the process via activity monitor and after a few hours, it started back again. And every few hours it kept doing it. So i finally deleted the printer it was sending to, since i have 4 printers installed. After that, it sent to the other one, and the other one, until i deleted all my printers. However, before deleting the printers, i saw what job trying to run, it said that MY USERNAME initiated the job and the file was called PYON.ps.... So, I delete all my printers. And now there is a new process cgfdtopdf.... Which i'm assuming it's trying to make a PDF file because there is no printer.... Is this a virus??
