Set preferences to ensure software updating is enabled.
Use the built-in browser security settings.
Disable popups in your browser or install software that will prevent popup windows if your browser cannot block them. Popup windows can be used to run malicious software.
(Internet Explorer only) Disable disk caching for encrypted pages. If content you view during a secure session is stored (cached) on your computer, the content can be exposed if your computer is compromised.
Install add-ons/plug-ins sparingly. Examples include Adobe Flash, Apple QuickTime, or the Google Toolbar. Some sites may ask you to install an add-on or plug-in so you can fully view the web site. However, the site may direct you to malware, rather than a legitimate add-on/plug-in. If you are sure you want to install an add-on, download it from the original developer. This helps to avoid malware.
