That's one of a couple of times[1] in my life where I felt what I think people describe as my blood freezing. I knew I hadn't installed that thing and I had no clue how it had gotten there and I too thought I had gotten some malware that even I had neither managed to evade nor caught immediately (I can think of two cases of the latter from the top of my head, one drive by on a completely innocent blog and one where a previously nice program suddenly bundled ad or malware).
Somewhat fortunately for me in the long run I am such a wasted brat when it comes to software that I had to forgive them - I can't stand working in Chrome or Vivaldi, and not only because I don't like Google because I did back then, but for my use cases it is so clumsy (the way tabs work, how it can't handle a few hundred tabs, how it still doesn't support vertical tabs etc).
[1]: the other time being when I had been married a couple of years and found a letter in the paper bin saying that one of my mortgages had defaulted - long story short it went well but I was shivering at the time).
