While surfing the World Wide Web, we frequently come across
pages that contain Java applets. These applets are small
programs, written by people that we often don’t know or
trust. However, their programs are being downloaded to, and
executed on, your machine.
The Java Filter lets you take control over which applets
you want on your machine and which you don’t.
The Java Filter gives effective protection against unwanted
execution of Java applets, without having to switch off
Java support of your browser. For example, you could only
allow applets from within your firewall onto your computer.
