In Windows Task Manager and AVG Task Manager (included in TuneUp Utilities), I see that the sum of all the running processes is much lower than the total CPU usage shown in "performance" tab. Does this mean that my PC is running a hidden process or some malware that's not displaying in the Task Manager?
EDIT: inbuilt monitor showing this too, and show processes from all users showing too. laptop is two-cores, and I'm taking total load of both.
