I received an email last night from a Buy.com that contained two links, one to my order and the other to track that order. Clicked on the first, because I couldn't remember what I had bought (I'd ordered from a couple of places yesterday). Well, everything locked up. Mouse pointer, keyboard, even the ctrl-alt-dele that allows you to get to the Task Manager to stop a process. Finally had to pull the battery in order to reboot. Am running a virus check now, just in case it was a diseased link. So far, haven't detected anything.
