But then, I heard that distinct, annoying "click" that Internet Explorer makes when it feels like it has accomplished something important, which can range from "I need your confirmation to go any further!" to "I made a mess on your couch!" What was odd about it was that I only run Firefox on my machine. After poking around my windows, I saw a popunder with the cheery message that a toolbar had been installed on my computer. This, much like when I cook for myself, set off all sorts of alarms in my head that I was in terrible danger. So I ran Spybot, and Spybot declared to me that I had a whopping 215 trojans that hadn't been there before. 215! I mean, the last time that many trojans were in the same place at the same time, Greeks were pouring out of a pinata and stabbing the lot of them.

Can't find a direct link, it's here though.
