Often, the address of the Web site to which you are misdirected will show telltale signs that it is an imposter. If you are asked to provide personal information on any site, check the address and make sure it starts with https:// instead of http://. (The "s" indicates that the site is secure.) Also, check for an "@" anywhere in the Web site address; if you see one, it likely means you are being redirected to a site other than the one you wanted to visit. Make sure the address has a .com when it's supposed to. Many sites will have an address similar to the one you intend to visit, except the .com might be replaced by .net. Unfortunately, seeing https://, the padlock, and the digital certificate is not always a guarantee that you're at a secure site and not a fake one. If you sense something is suspicious even when you see these security indicators, please contact a TD Ameritrade Client Services representative right away.
