The fixed version of Adobe Flash Player was released because of corresponding to the critical security vulnerabilities, issue of IE9, and issue of MacOSX Lion. Adobe Flash Player has been frequently updating, so I strongly recommend to access to the following version check site.
If you use not only Internet Explorer but also other web browsers, please check 2 browsers of Internet Explorer and one of other web browsers.
* If you don’t know Adobe Flash Player, you can use it without thinking when you access to a web site. Adobe Flash Player is the plugin software for playing the Flash contents, such as the menu, animation, video in a web site and so on. Therefore, almost machines except iPhone/iPod Touch/iPad are influenced.
