There is little chance that a Windows virus infected that Linux system file. It is most likely a false alarm, though you are the first to report it. Since it's a system file, you definitely don't want to delete it. You could do an OS re-install, though I'm not 100% sure that will overwrite that file with a fresh one.

/var/cores/core-systemd is a core dump, not a system file. It is safe to delete anything in /var/cores (but don't delete the folder itself).

Thank you StephenB and Sandshark. I have reported to the AV company.
Not sure how to access those folders on the NAS side.
Best regards,
Razvan

You'd have to use the ssh (the linux command line).
Do you any experience with that?

If it's a core dump, then it's unique to your NAS and reporting it will do no good. It also explains why nobody else has reported it. I still think it's a false alarm, but since it's not executable, it will do no harm no matter what. I wouldn't think the NAS would keep core dumps forever, though. Maybe StephenB knows if they are automatically deleted periodically.
