Whatever the combination, I'll blame the site I visit. I've seen bad ads on imgur one time I used the Internet without blocking ads. The ad just started downloading "Firefox patch" without me clicking anything. It is not black and white but it is pretty close. Edit: I have to give Firefox credit here. It actually just prompted me whether I'd like to save the file. I did and uploaded it to virus total. Probably not a good idea if you do anything sensitive on your computer.
