I downloaded Firefox, then when it was done two new apps called Ot Shot and PC Fix Speed appeared, i recently had a blue screen and think i got a virus

Question

I think i may have gotten a virus from downloading firefox

Answer 1

The '''Mozilla.org''' Firefox installer only installs the Firefox program.
Where did you get your Firefox? You should get the program from
'''Mozilla.org'''. If you got it from somewhere else, it may have been hacked.
Try to remove all of those programs using the Win Uninstaller.
====================================================
