Windows Server 2016 comes Windows Defender Antivirus

Their ATP offering is really solid. Mainly because it isn't made by Microsoft
I forget who they bought it from, but our MS sales reps were telling us that they bought a complete product.

But does Windows server allow you to install AV on the server with Defender ? feels like it this day an age it will penalize any 3rd party software.

I know some AV programs clash, but I don't know about Windows Defender. It's all I'm using at home and a few of my servers (Server 2016) at work.

Depends, if it is a Windows file server, I would generally like to have it. Other than that, I normally don't. We rarely run Windows on servers, so that generally solves the problem right there.
And in case of a Linux fileserver? I did that, not a big problem.

ClamAV if you feel the need

Not normally, the end points do it already.

But wouldn't that mean that you actually trust your endpoints?

I don't trust anyone using legacy file serving

Or... maybe it is that I don't care, let the helpdesk deal with those issues

I think it's only useful if the server is hosting files that Windows clients will be using. If it's non-windows from file storage to clients then I don't think it will make much difference.

Defender plays nice with webroot, can't speak for other AV programs.

I run Webroot on some http, Exchange, CRM, MSSQL, file servers here without issue.

Nope, that's why I run an IDS like Wazuh everywhere I can.

AV on a file server only protects against users stashing malware on there.
For example, if someone's homedrive has malware.exe in it, the AV running on the file server will kill it.
This is file server OS agnostic, and should be on there regardless of OS. Simply being Linux does not protect against this.
You can't count on client OSs to keep fileservers free of malware, so you definitely need it on every fileserver.

Well, my point was simple: If you don't protect your server too, you automatically trust either your clients, your IDS or both, whatever applies. If you put AV on a fileserver, you don't need to worry about proper AV - in terms of malware - on your IDS or clients, you check the files on your own.
For example, if someone's homedrive has malware.exe in it, the AV running on the file server will kill it.

OK, you basically wrote the same here

Yeah, the fileserver being Linux has no bearing. A file server is a file server. Users can put whatever they want on there, if they have write access.
Nobody plays on the fileserver itself, and most likely no GUI, so you don't need protections for that reason.
You just need a way to keep your directories clean and free of infectious files. There shouldn't be because a users computer accessing the fileserver in the first place should have the same AV, so from that point of view I can see why the server itself wouldn't need anything.

For file servers, do you have your antivirus set to on demand and have it on quick and full scan schedules?

I put AV on all file servers. It never fails that it eventually finds things. It has in every case so far, which it shouldn't because all endpoints connecting to the file servers have the same AV the file servers use.
But to answer your question, it does different scans depending on the situation. I forget exactly what they are now without looking... But one is like after every definition update, a quick scan of some sort. A quick something after boot up, a full scan at some point. I'll have to look to get more specific.
I could be completely off, I don't remember.

It comes down to security vs. convenience. Performance is something completely different and can be tuned/scheduled.
Do you leave your keys in your vehicles ignition? Do you leave your front door wide open? Do you write your personal identity numbers on your arm?
No? Use anti-virus.
