Some security bugs inside Java allow rogue programs to access your computer and your files by simply passing through a Java program without notifying you anything. If you do not use Java, or if you do not know whether or not you use it, the easiest solution is to uninstall it. If you use applications for desktop, we recommend you to disable it for web applications. Finally, if you still need Java for web applications, it is safer to use two browsers: one dedicated to Java applications and the other for all other activities on the Internet.
