Computer settings like site timeouts and pop-up blockers can reduce the chances of someone hacking into your computer.

Your cache is a location on your hard drive where Web information is temporarily stored. When it is stored, it allows your browser to quickly re-load Web pages. While this helps your computer display Web pages faster, it also stores information about what you've been seeing on your screens, which might include personal and/or financial information. It's therefore a good idea to empty (or clear) your cache regularly so that this information isn't readily available to hackers.

Pop-up blockers are software programs that keep advertisements and new windows from popping up on your computer screen. Although usually just aggravating, some pop-ups display inappropriate content, while others can be dangerous to your system.
Using a pop-up blocker reduces the potentially harmful threats. For maximum safety, consider changing your pop-up blocker to the highest possible level. But please recognize that our site does contain pop-ups, so you'll have to account for this.
In order to view all information on the site, including most forms, results for symbols and quotes you look up, and the Streamer SuiteTM tools, you must do one of two things: add the TD Ameritrade Web site to your ist of "trusted" sites, or disable your pop-up blocker while you're on this site. Adding the TD Ameritrade site to your list of trusted ones will allow pop-up windows only from this site (and any other sites on your list).
Many browsers, toolbars, and Internet service providers (ISPs) include pop-up blockers as part of their service, so you may have one operating on your computer without realizing it. Check your pop-up settings to help make sure you're safe, and TD Ameritrade to your trusted sites.
