What is the a5 process? In activity monitor. I am in no way new to mac but i have been having some weird problems , anyone bother to help me? My iSight green light turned on for a very brief moment, my disk space went from 150 GB to 0 MB in less then a second, and in the about this computer it said Everything was others. No pictures, programs whatsoever. And then my launchpad randomly got reset, and stuff. It feels like i have some kind of malware .
