Windows 10: Trojan: 100% CPU usage: When I open task manager it from 100% to normal.

I believe I may have a trojan, while I'm on my PC, the fan is extremely loud. and when I open task manager, it goes back to normal, I've had this for a few weeks, and I've noticed that it has just deleted my anti-viruses, can someone help? I have a really beefy laptop so I know it's not that, and I've never had it until a month or two ago.

Opening Task Manager Changes CPU Usage from 100% -> Normal (Windows 10). [SOLVED]

>>> But that still doesn't explain why the processor is running at 100% before I open it.

well if task manager is CLOSED, how do you know it is at 100% ???

Then you OPEN it, and it instantly drops from 100% to normal 5%.

HUH ???

That makes no sense. And opening Task Manager is not going to drop processor usage from 100% to normal just because Task Manager is now open.

The only way tis is possible, is if Task manager is corrupt. But I have never seen such a Thing on Thousands of PC's in 20 years.

yes, moving wireless mouse will cause little spikes too.

But never heard of or seen the usage at 100% and then open task manager and it drops to normal. Seems IMPOSSIBLE.

And I asked him, how does he know it is at 100% before he even opens task manager ??????????

That is the million dollar new question. And got no reply back!

 

Cpu usage high until I open task manager

So, whenever I open my task manager CPU usage is at 100% and thing that takes up 100% is something called " system interrupts ", but its only when I open the task manager, so when my task manager is closed my CPU usage is at 100% at all the times? Do
I need to keep my task manager open to play games?...
