Hello, lately i have been having problems with my computer shutting off. I know it is not over heating seeing as though my computer is cool and my fan is on high right next to it.

However today i seen a icon in my taskbar with 3 green bars with a black OUTLINE right before it shut off.

I find it suspicious and think a virus is wandering around in my computer.

I need answers ASAP because i cant feel SAFE when i think a virus is fiddling around with my computer while i'm surfing the internet.A virus isn't gonna create an icon to let you know it's there...
How do you know it's cool ENOUGH ? ?...where you getting your temp readings from ? ?I'm not fully sure everythings cool in the computer but the icon that appeared was making me suspicious.

I just opened up the computer and looked at EVERYTHING. Only a tad bit of dust was in there which couldn't MAKE anything overheat.

The computer isn't very old either.

Actually i just checked something with malwarebytes and detected something. I am willing to give a screenshot of what it is and if its what was causing the problem.
