You should also have a little icon in the bottom toolbar that looks like a locked lock when you are on a secure site.
Here is a website where you can download a security program that will do what it says below. It's safe and is added protection.

"Rapport detects and prevents Man-in-the-Browser, Man-in-the-middle, phishing, and other attacks launched directly against the user. The Rapport service includes a lightweight browser security plug-in, as well as cloud-based analysis and reporting services. The browser plug-in works with all major browsers, including Internet Explorer, Firefox, Safari, and Chrome. When users browse to sensitive websites such as online banking, Webmail, or payment pages, the Rapport plug-in immediately locks down the browser, and prevents any unauthorized access to web pages and sensitive information that flow through the browser. This browser lockdown is achieved through a combination of access control, encryption, and verification technologies that take place in the background, completely transparent to the user."
