I'm getting a pop up when I try to navigate around this site that locks up my entire computer. This is different from the re-direct problem, but far more troubling, because I can do *nothing* except power it down using the power button. I didn't think to take a picture of the site it's trying to take me to, but I will if it happens again. It's something about "your software needs updating", and it's not the regular update alert for my OS. I'm using a MacBook running OS X Yosemite, if that matters.
