Unfortunately I’ve not yet got Antivirus on the Server. So, having a bit of time on my hands I hit went to Symantec, since Norton Internet Security has served me well over the years.
It was not to be. Their server products are only available in 5 user license packs for some reason. And it seems their US store is cheaper than the UK store. I spent 20 fruitless minutes looking for the server products before finding them buried at the bottom of the products menu. The US store sells 5 user licenses of Antivirus 10.1 or 10.2 in 5 user packs for $47.69 and the UK store only sells it as part of a package for Small Businesses for £200+. No use to me.
I tried McAffe next. McAffe sells a minimum of 2 licenses for their Total Protection product for Small businesses for $64.79. The UK store sell the same product only in a 5 user license pack for £59.52. Now if you take the exchange rate in to account there is only about £30 difference between them. But I would be buying 4 licenses that I don’t need.
Over to AVG. More of the same. Again 5 user licenses for £211 for a year. Waste of time since I’m looking for a single license for a single server.
Trend Micro don’t sell their Small Medium Business offerings online.
So this is essentially a wild goose chase. So if anyone has managed to get a single license of a serve edition antivirus solution, please let me know in the comments.
Random Musings 
can you not try a trial version for a whilst, or even contact the PR team. They might provide you with a review copy, for this blog, and for your needs
Good idea. I’ll give it a try.
Unfortunately the Norton product you found would only be for network client PCs, that price does not include the server software which is a LOT more.
One of the problems is that virtually all single user packages would be for a workstation software base and will refuse to install on a server kernel as with WHS.
I have been using the Avast WHS product for a while as this seems to be the only viable offering but I am less than happy. The client side management is poor to say the least and the tech support is dire to say the least.
