This method of entry is commonly executed via your Web browser. Often, the attacked will exploit a flaw in a piece of software, known as a plug-in, upon which your Web browser relies, such as a PDF viewer or a Java application. It's often difficult to ascertain exactly which plugins you have present on your computer and which version is the most secure to use.

To help you more easily manage your plug-ins’ security, Mozilla has put together a web page to evaluate what you have installed and its version. It will then let you know if and where any upgrades are available for any plug-ins.
