I'm not sure about any windows based solutions but you might want to check out Dansguardian - http://dansguardian.org/
It has a AV addon - http://www.pcxperience.org/dgvirus/ that will scan the content before passing it onto the clients. I should note that there is still a possibility that the client will receive the virus before it can be intercepted. The problem is the proxy has to download the content first and scan it before it can pass it on. If it takes the proxy too long to download and scan, the client could time-out waiting for the proxy to forward it on. To get around the problem, the proxy sends some of the content to the browser, usually 1 Byte every minute and that seems to keep the client happy while it waits for the rest of the file. There is still an extremely small chance though that part of or all of a small virus could get passed to the client when it does that depending on how big the file is and how long it takes to proxy to receive it and scan it. Another solution is mod_clamav which is a AV mod for apache2 that uses ClamAV to scan for viruses. It's the same kind of thing except it just uses apaches proxy code instead of using an actual proxy application. I know for mod_clamav you can set it to not scan files over a certain size, I'm not sure about the Dansguardian one though.
