  • Did you check this question? http://stackoverflow.com/questions/1264891/server-side-virus-scan-on-a-file-for-windows ? Is server side but I doubt whether it is possible in client side. – Shoban Apr 10 '12 at 04:43

You don't.

You scan it at the server, and delete it if it doesn't pass. There's no way to know if the client side has any AV software installed at all, and any result you got could be faked anyway. Do your checking on the server side instead where you have control.
