Piracy

So I've heard that this is the best website for watching movies, as it doesn't have any ads and doesnt redirect you anywhere or anything like that. However, the site plays videos from other sites, which do contain malware, and I've heard that you can get a virus from simply playing a video online. So while movie-web itself won't give you a virus, will playing a movie on it give you one (assuming you don't have an adblocker)? Thanks.
