My Vero 4K gets quite warm when idle

Thing is - my Very has a load average of 0.12 → 0.14
while your’s around

however, looking at your output, I don’t see the process that is actually causing the load, which leads me to rather think you have a trojan running on your box.

do you by chance have your Vero accessible from the Internet, and did you not change the password?
In that case - I rather think you got yourself the mining malware.
Check it out, it is quite recent:

In that case, my advice is to reimage your Device and change the password straight after the reimaging process is finished - then reconfigure it.
Also - make sure it cannot be accessed from the outside.

If that is not the case, You need to provide a full log for us to check what is going on.
