Firefox seems to be doing okay, but whenever I open Safari and Chrome they always end up opening up a separate tab, and they are sites like mackeeper, or some other annoying pop-up scam. I've tried uninstalling chrome, resetting it, and clearing all the browser history. While with Safari I tried to follow the instructions on the apple support site, of locating the activity monitor, quitting the activity, but I can't find anything that says "mackeeper" or any sort of variation of that. I don't want to just go download something and make it worse, so I'm wondering what I can do to get rid of the adware, malware, whatever it is. Thanks!
