I clicked on a link in Digg yesterday, and the next thing I had pages full of popups (I use Firefox). Lots of the popups were warnings "you might be infected". I cleared all the private data on Firefox, but this morning when I tried to send an email through Thunderbird, I got a warning that my mail was being redirected and it refused to send. Any ideas of what is going on, and any solutions? Honestly, I've been a PC user for ten years and only once had this happen, and thought I was pretty much immune on a Mac, I guess not.
