New exploits and security holes in web browsers are found almost daily, and browser manufacturers update their products frequently. It is important to make sure you have the latest version of your web browser not only to ensure your security, but also to ensure peak performance and compatibility:
Obtain the latest version of Internet Explorer by clicking on the Tools or Security menu, then select Windows Update.
Obtain the latest version of Mozilla Firefox by clicking on the Help menu, and then click Check for Updates.
Obtain the latest version of Google Chrome by clicking on the "Wrench" icon in the upper right corner of the window, and click About Google Chrome. If an update is available, a link will be available on the bottom of the About window.
If your web browser is not listed, please check with the manufacturer's web site for updates.
