Microsoft's Forefront Client Security doesn't install on Windows Server 2008 R2. I'm talking specifically about FCS without update server that updates via Windows Update:

clientsetup /nomom

This installation doesn't work on a server operating system. Hence the question.

So the question is: Which realtime antivirus is Windows Server 2008 R2 installable?

What do you mean "doesn't work"? Obviously, you got a virus. Was it through e-mail? Was it a worm? A server exploit (in which case it wasn't a virus but a hacker)? You say you're running a server, but does anyone ever sit at it and use it "manually"? Do you know what virus it was? – Ernie Aug 18 '09 at 14:57
It's worth noting that every antivirus solution has a period between virus creation and virus discovery and software update during which you can get infected. There's no such thing as a perfect antivirus product. – Ernie Aug 18 '09 at 14:59
the key word in the question is "realtime" I guess, that is the ability to check files "on the fly", or, phrasing it in yet another way, check all files in the background as soon as they are created or modified. This sometimes is called file system hooks. In this sense, this question is perfectly valid – dmityugov Aug 18 '09 at 17:32
I've just setup the system and am using it as a power workstation. So there's a person behind it. :) – Robert Koritnik Aug 18 '09 at 18:33

We like NOD32 has a centralized management console, push installation and global rules that can be configured from a admin location.

Yes but it can't be installed on a server OS can it? At least not the antivirus. – Robert Koritnik Aug 20 '09 at 12:13
Well I found out that NOD32 Antivirus Business Edition DOES install on a server. I'm now using it for some time and I'm really happy with it. – Robert Koritnik Nov 1 '09 at 20:37
Though the System Requirements for NOD32 Antivirus Business Edition doesn't state that 2008 R2 is supported? – SteveBurkett Dec 18 '09 at 12:07
NOD32* works great on Server 2008 R2. (* yes, the 64-bit version is still called NOD32) – Skyhawk Jul 30 '10 at 16:10

Your question is exceptionally poorly phrased. "Doesn't work" tells us nothing. Is there an installation problem? Is it giving run-time errors? Is it that a virus got through?

To Channel the IT crowd "Please state the precise nature of the problem".

Assuming the issue is that a virus got through - that can always happen. No AV is perfect because they can only detect known threats. Those threats only become "known" AFTER they have infected machines. They are purely re-active, so they can never be perfect.

Also, there are technique attackers use to disguise even known malware through "packing", so even known threats can be disguised to get through AV.

There is no silver bullet.

I'm sorry. I clarified my question now. Thanks for pointing this out. – Robert Koritnik Aug 18 '09 at 18:32
Cool, that much better and much clearer now. Unfortunately, I don't have an answer for you now that I know what you're looking for. Sorry. – Bart B Aug 19 '09 at 9:29

Newer versions of Forefront Client Security will install on Windows Server 2008 R2 x64. I just finished an install today of a standalone, get-updates-from-Windows-Update installation of Forefront Client Security on W2008 R2 and it worked fine.

Note that you'll need to run the clientsetup /nomom in the \CLIENT\x64\ directory of the installation media. The clientsetup.exe in the \CLIENT\ folder won't install on a 64-bit OS.

We're pretty happy with the offerings from F-Secure. We use it on workstations, servers and mobiles.

Scratching my head on why this was downvoted. If one hasn't had good experiences with F-Secure, why begrudge someone who has? – Wesley Aug 18 '09 at 19:23
I was wondering as well. Out of all the commercial products we've tried, we've had the best luck with F-Secure on many levels, but of course your mileage may vary. Every product out there will have problem environments, it's just the nature of the beast. – palehorse Aug 18 '09 at 22:01

Well first of all make sure not to go to suspicious websites. install mcafee and update it EVERY 12 hours!

share|improve this answer
In fact, don't go to any websites. It's a server. – MDMarra Aug 18 '09 at 14:41
Firewall, anyone? – Ernie Aug 18 '09 at 14:53
I'm sorry, but McAfee is the one of the most bloated crap-ware there is (Only Norton is worse). – fretje Aug 18 '09 at 14:56
McAfee VSE has improved significantly since 8.7i was released. They have also released a management console for EPO to start weening people away from the clunky web interface. – MDMarra Aug 18 '09 at 21:05
@Ernie, What is a firewall going to prevent in the case of browsing suspect websites as an admin on a server? (note: if you actually do that, you probably deserve whatever you get, just hope you're not running as domain admin) – MDMarra Aug 18 '09 at 21:06

If you're specifying Windows Update - that's only going to distribute to Microsoft products. Ruling out MS AV makes this a self-canceling question, unfortunately.

My humble suggestion would be that if you need 2008 server on your workstation, do your web browsing from within a virtual, where you can install a client OS - which will be supported by a huge array of AV clients. Fitting a square peg into a round hole doesn't seem worth it.

I'm not specifiying it has to update itself via Windows Update. Only FCS does that. I'm looking for alternatives. – Robert Koritnik Aug 20 '09 at 12:14

Probably a real shortage of released products that work with 2008 R2 at the moment, but Kaspersky has a release candidate available of their Kaspersky Antivirus 6.0 MP4 product, release notes here stating Windows 7 and Windows 2008 R2 support. You can grab a version for testing.

share|improve this answer
Indeed they released MP4 of Kaspersky Anti-Virus for Windows Servers a while back, seems to work well with 2008 and 2008 R2: More info : – SteveBurkett Dec 18 '09 at 12:00

Clamwin works on Server 2008 R2 Enterprise
