Do not follow links provided by unknown or untrusted sources.

Web users should be wary of visiting links provided by untrusted or unfamiliar sources since this issue may be exploited by a malicious Web page.

Set web browser security to disable the execution of script code or active content.

Disable support for client-side scripting and active content in the Internet Zone. The vulnerable DHTML methods require client-side scripting to be invoked.
