Processes that did not exist before, where do they come from?

Question

System administration

Hello!
I deployed a VM (proxmox host machine, ubunt OS 18.04)
looked at htop out of habit and was surprised at the processes, hence 2 questions:
1. If not a virus, will the processes kill the ssd disk ahead of time?
2. Can there be viruses?
PS It was not the first time that I installed the system from this isoshnik, in this case I installed the minimum necessary programs on a clean OS and made it a donor for further cloning.

Answer 1

If it's not a virus, won't the ssd processes kill the disk ahead of time?

They won't kill before time. If the task of the process is to kill the ssd, then it will do it on time.

Could there be viruses?

They can.

Answer 2

These are kernel threads. The line Tasks (in the picture on the top right) says 78 kthr; - it's them.
With an SSD, as the card falls.
Viruses may be.

Answer 3

Processes Need to
kill
Warranty on them for a reason

Answer 4
