Pros & cons? I'm considering enabling it on our new qnap @ work. I'm running it on a distro at home. Don't think it's ever flagged a problem, or had noticeable effect on performance. Only time I'm even aware of it is during email scans, or during system updates.

On the qnap forum a couple of people have flagged scan slowness (though I'd schedule it for night), high cpu usage and conflicts with other scheduled tasks, rebuilds etc.

So I'm inclined not to enable it. Does the (minimal AFAICT) security benefit make it worth the (potential) other issues?

edit: windows boxen will be connecting to it, so...

I run it on my QNAP. Can't say I've noticed any performance hit, but then I mainly use it for backup.

Why not suck it and see? You can always disable it later.

My biggest fear is that it might cripple a rebuild. The thing is going to be used in production, not backup. It dropped an apparently fine disk early last week, 'found' it again on a reboot and took ~7-hours to rebuild (during which it was still accessible in 'degraded' mode).

I've since enabled volume bitmap, which is supposed to make rebuild in such a scenario much faster.

It's so much more fun to put a server into production without thorough testing

What has clamav done for you lately?

Oh, I dunno, the usual I guess. Scanned for viruses, updated itself to current virus definitions. Should I expect anything else?

Found any viruses?

Put working AV products on the Windows boxes and don't waste the resources, time and effort on ClamAV.

No. Which means either it's not working or my QNAP has none. Does that help?

Yeah I think so. From what I've read, cav has more value on a mail server.

From what I've read, it has almost zero value.

I mean, it might protect you from as much as 50-60% of viruses, but simply not downloading from dodgy sites and not opening unsolicited attachments has a higher protection rate than that.
