Description
Java applets exist both signed and unsigned. Even for signed applets, there can be many sources, some of which may be purveyors of malware. Applet sources considered trusted can have their information populated into the browser, enabling Java to validate applets against trusted sources. Permitting execution of signed Java applets from un-trusted sources may result in acquiring malware, and risks system modification, invasion of privacy, or denial of service. NOTE: The 'JRE' directory in the file path may reflect the specific JRE release installed.
