Although Adobe Flash enables website developers to deliver a rich multimedia experience to their readers, many websites use Flash to deliver annoying ads. Flash ads can be displayed in pop-up windows, as well as on the same Web page. Furthermore, some flaws in Adobe Flash can be exploited by hackers. You can block Flash in Internet Explorer 11 by disabling the built-in Flash add-on. Alternatively, you can use ActiveX Filtering to enable Flash for trusted websites. An ad blocker add-on is also useful at blocking all kinds of ads.
