CMD at startup

[cobrano]

Hi
Today i turn on my machine and when it automatically logged in to windows 10, after a while a cmd window appeared for about a second (i am not sure if it was it, the monitor blacks out for a second every time when loading nvidia driver) so i made a check with windows defender (short check) and also i installed malwarebytes and it also didn't find anything. I have only Intel and Microsoft tools added to 'automatically launch when windows loads'. My question should i be worried if it was a cmd window? I read on the internet this means the computer have virus but as i said malwarebytes didn't find anything
Thanks

Is the cmd window coming up on every time you reboot the pc?
It might be some command that runs only once to finish some installation.

Anyway - check start-up items in Task Manager.

Thanks for your answer, i think i don't have to pay attencion, it could be everything, but not a malware
