The new PluginCheck utility provides security for the user, protecting users from security vulnerabilities and ensuring that they benefit from the latest bug fixes, pretty much automatically. It blocks vulnerable plug-ins from loading, and provides users with the information oh how to update the software, right at their fingertips.
