Do you love watching videos on Facebook? Facebook is giving YouTube some serious competition as the go-to place to watch videos. But one of the ways users watch videos on Facebook has a serious security flaw. I'll explain and show you what you need to do to stay safe.
You probably haven't heard of Unity, but it's a piece of software that works on PC, Mac, Linux, iOS, Android, Windows Phone, and just about everywhere else. It lets a software engineer design a game that can run on multiple gadgets and systems. That's handy for the game maker and let's users enjoy games on the gadget of their choice.
Unity also has the Unity Web Player that lets certain games and sometimes video play in your browser. NASA has used it to let you drive a rover on Mars, for example. You'll occasionally run into it on Facebook and other sites around the Internet. Unity claims that more than 200 million people have it installed. You may use Unity and not even know it. I'll show you how to check if you have Unity installed.
Unfortunately, a serious security flaw has been discovered in Unity. Any version of Unity prior to the just-released 4.6.6 has this problem. It could let a hacker snoop on your Facebook, Gmail and other Web traffic, or even read files off your computer if you're running Internet Explorer.
Fortunately, this problem is easy enough to solve. You can either download the latest version of the Unity Web Player here, which includes the fix, or uninstall it from your computer.
To see if you have Unity installed, go to the Unity Web Player page and look to the right. It will tell you the Unity Plugin version, or say "not installed" if it isn't installed.
To uninstall Unity if it is installed, go to Start>>Control Panel and under "Programs" click the "Uninstall a Program" link. Scroll down the list to find "Unity Web Player." Click on it and click "Uninstall."
