That reminds me of when the Melissa virus hit the servers at work. A week after our boss had told us to be extra careful of what we clicked and we should update.
Staff arrived at work, since we had looked at the online news, before arriving at the office. The staff in the Sydney office was telling us, via ICQ, it was circulating. It was at hand if you applied the update that could remove it before you fired up your email.
Which we did and nothing really happened other than sharing news stories how other companies got hit hard.
Then the boss arrived in the Paris office, were I was at the time, and we all got infected emails from him via the various mailing list etc. As you said Ham sooo many middle management people started to hit reply all to tell us that there was a virus and we should be careful.
Until the IT fella found the Boss and unplugged him and a few others that was dumb enough to click
Then the UK office opened up and for some reason they were a wee bit dumber than the Paris office. Which caused our IT fella, the company's top IT guy, unplugged us from the internet and went desk to desk. I'm sure there were a few angry phone calls to the UK.
Then the US office opened ... and our IT fella went ballistic and walked out of the building, after he shut down the company mail server, as he had just managed to control the fall out in the UK and France.
