Recently I've had this bizarre occurrence where I'll be browsing MMOC (not clicking anything) and the page suddenly changes to a fake McAfee scam page with half a dozen fake popups that are trying to get me to click on them. It's happened twice in the span of 2 days.
Could an ad or some kind of weird script inject be the culprit? I haven't had this problem elsewhere and I usually have 20+ tabs open at any given time. I'll try to take a screenshot the next time it happens.
