[Snort-users] SMTP Virus Gateway

I've always used McAfee WebShield SMTP with great success. Then again, I also do a blanket drop of all .exe, .vbs, .bat, etc.
Virii are ever-changing, and are spreading faster and faster. And as many improvements as we've seen in AV, we're still seeing large-scale global infections. Given these conditions, I can think of *very* few excuses for an administrator to continue allowing the aforementioned attachments (and others, not listed for the sake of brevity). At some point folks need to learn that the software won't always save your a**, and that we need to start being intrusive/proactive.
In short, we could spend weeks talking about which AV gateways let which virii pass through the filters, but it's largely irrelevant. The problem *can* be fixed. Getting back on topic: McAfee (properly configured) works great for me, and always has!

NOT Norton AntiVirus gateway. I can't speak for anything except the
version I use but if the company handles any other version the same way
I'd stay away. Both SirCam and Klez come right through. I already had to
upgrade once for SirCam, I'm not doing it again. I need to find a new
product as well.
