My wife has a small laptop, the HP Pavilion G6 I mention in the title. She uses the thing for mail, a little social media and various handiwork sites, (she is a handiwork teacher - junior school level right now). It runs under Windows 10. It is how it runs that my question revolves around. Using the task manager, I can see that the CPU is running at or very near100% busy all the time, it is the fan that drew my attention to this, I am in another room and can still hear the thing. There are A LOT of things in the task list, but few are using any CPU, yet it says 100%, and nothing there looks obviously wrong. What is this thing doing? I am starting to worry that she has picked up some undesirable hidden stuff that is pumping out spam or worse.
