We are an ISP as well. I tried to implement a filter very similar to Wil's. However, our users went ape shit. So I just filter our office traffic. You would not believe how many users add our accounts or help alias to their address book. We get hundreds of infected e-mail's daily. We send out a weekly usage report as well, and get a ton of "viri" via RE: I think it's safe to say that we have had over 500 calls in the last two weeks regarding virus's. It is AMAZING how many people install virus protection and say " you mean I have to update it?" " I got the virus?, But I have NAV, how is that possible?" " When was the last time you updated it?" " I have to update it?" AAAAAAAAAAARRRRRRRRRGGGGGGGGHHHHHHHHHH!!!!!!!!!!

As it is, I'm catching lots of greeting cards and crap like that with the .exe. Wil -- W.
