I had it happen yesterday at work. My Daughter looked at the site the microsoft pop wanted me to click on and she said don't do it the link didn't look right. I don't remember what the address was but it seemed strange. I was on this site. I got a real bad trojan horse virus, computer had to be reset to factory specs and everything re-loaded. That was a couple of months ago. What a pain in the tush. I was on this site too and I clicked on a link someone had put in their post. an adobe update appeared, dumb me clicked on it and that is when it was installed on my computer. I'm not always quick enough to pick up on everything.
