Miner detecting in windows 10

[RokasM]

Hello, my PC CPU load randomly spikes upto 90% and stays like that. When I try to start task manager it goes back to normal load, so I can't see what causes it. I tried scanning with Malwarebytes, didn't help. Tried searching for it in msconfig, didn't find anything either. Can anyone suggest any software to find that virus, or the only option is trying to reinstall windows?

Try running Autoruns from https://docs.microsoft.com/en-us/sysinternals/downloads/autoruns. Look through it and see if you can spot and software you don't immediately recognize. If you're not sure what you're looking at, send over a screenshot.

how do you know your cpu spikes to 90% if you can't see it in task manager? also, if task manager solves the issue, just keep task manager open all the time.

I use "Open Hardware Monitor" for monitoring temps and loads on my PC. And keeping task manager is not an option for me. If there is a problem I need to remove it.

Did you run Autoruns like @PorkishPig suggested?   If not I highly suggest you do as it will tell you a lot of information about what's set to run on your system.  It's much more detailed than Msconfig. 

 

There are some other tools you can use to find deeper malware, and even malware that's not on a signature database (that's if there IS a miner).  But run autoruns first and let us know what you find.

I ran Autoruns as @PorkishPig said. Snd found some kind of doenloader. Disabled it and it helped. Thanks a lot for help!
