Drunken Owls and Other Delights

We had a couple of incidents recently where systems went down, followed by a warning e-mail for idjiots about not clicking on the link to the electronic greeting card they had received.... I wonder if someone in your system fell for something and managed to infect your system. While I never heard that we were infected, I did hear about infected computers at the same time we were having problems so am guessing that was the problem.
