Websites can inject malware irrespective of ads. Not to mention that ad blockers, themselves, are a good vector for exploitation. (Another consideration, obviously, would be to avoid websites that show you ads that you don't like (or fear) rather than circumvent their only path to revenue.) I generally count on Google (and Chrome) to prevent that. At the risk of jinxing myself: I've never had malware installed on my computer view a website.
