Whatever the combination, I&#x27;ll blame the site I visit. I&#x27;ve seen bad ads on imgur one time I used the Internet without blocking ads. The ad just started downloading &quot;Firefox patch&quot; without me clicking anything.<p>It is not black and white but it is pretty close.<p>Edit: I have to give Firefox credit here. It actually just prompted me whether I&#x27;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.
