They say that allowing the "odd" file extensions will allow viruses to get in.

We have a crappy IT department and we got hit really hard with the last two that came thru. We lost two whole servers and were down for several days. (when you bill several million/week this is NOT good)

When the warnings came out about the viruses nobody took precautionary measures.

I have a feeling there are a few roasted butts around hear. And you can feel and see the smoldering coals on the fire!
