Thanks for the responses. I am mainly dealing with educating the faculty, as student machines don't really contain much sensitive info, and if one happens to get infected, we will just re-image it. We use mainly Macs here, so infections are rare/nonexistent. We had one that got that scareware Macdefender, but other than that, we haven't seen much. Macs just aren't a large target... [as you all know]

I am trying to help teachers avoid scams as well. Not just at the school, but at home too. I encourage them to send me examples of scam emails so that I can put them on the wall of shame. I think they enjoy reading some of them.
