You all probably know this allready, but for the love of God, don't open any attachments this week unless it's something you're expecting. There's a nasty virus going around. I've got about 3 kadrillion of them in my hotmail inbox right now. Specifically, don't open anything sized 75 or 76 kb.
Update: It's called the Sober virus. Here's a BBC page on it. Notice how the article has a picture of Paris Hilton for illustration photo sex-appeal, while it's all about how the virus email lures unsuspecting young men to open their attachments, looking for videos of Paris Hilton, seeming to say: "but we, the BBC, would never, ever do such a thing. Oh, how horrible, to use the poor young woman in this vicious manner."
