There is a big debate about uninstalling Adobe Flash Player completely from your systems or not. Unfortunately, Adobe Flash Player has been found to suffer by a number of vulnerabilities and new ones surface each other week.
If you still want to keep flash player on your system, I suggest you change your browser* settings and make sure any flash content runs after you have authorised it by clicking on it and not automatically when you visit a web page.
I also suggest you make sure you have the latest version of Adobe Flash Player which YOU MUST ONLY download from the Adobe website and not through any random popups or third party links.
This is the official URL where you can download the latest version of Adobe Flash Player for your system and the browser you are using is https://get.adobe.com/flashplayer/. Please note that you need to run Windows Update in order to download automatically the latest Adobe Flash Player update for Internet Explorer. I suggest restarting your system before you run Windows Update and after you have completed patching your OS through Windows Update.
By visiting the following link you can check if you are running the latest version of Adobe Flash Player: http://www.adobe.com/uk/software/flash/about/
* Make sure you have updated your browser (Firefox, Chrome, Opera, etc.) to its latest version before updating the flash player. In order to check if you have the latest version, run your browser, hit the Alt key from the keyboard, go to the Help menu and select the "About" option. Your browser will inform you if it is at its latest version or it will start downloading the latest version for you.
