How to enable JavaScript in Internet Explorer 5.x or 6.x higher, Mozilla firefox and Google chrome?

Many Anti virus disable javascript in browsers because JavaScript code can run locally in a user’s browser (rather than on a remote server), the browser can respond to user actions quickly, making an application more responsive. Furthermore, JavaScript code can detect user actions which HTML alone cannot, such as individual keystrokes. Applications such as Gmail take advantage of this: much of the user-interface logic is written in JavaScript, and JavaScript dispatches requests for information (such as the content of an e-mail message) to the server. The wider trend of Ajax programming similarly exploits this strength.

Sometimes we need to enable javascript to make full use of web pages.
