Years ago I got an ASUS eeePC 901 and hacked a copy of WinXP onto it. Yesterday I fired it up and it goes to 50% CPU with no visibly active processes in task manager, only when the network is running and it can see the internet. So that's almost certainly a virus with no way of fixing it. I can't think of any easy way to load Win10 and can't really be bothered when the machine is dog slow anyway.
Time to burn it with fire I think, before it does any harm.
