Answer to Question 1:
Answer to Question 2:
A secure connection is an encrypted exchange of information between the website you are visiting and Internet Explorer. Encryption is provided through a document the website provides called a certificate. When you send information to the website, it is encrypted on your computer and decrypted at the website. Under normal circumstances, the information cannot be read or tampered with while it is being sent, but it's possible that someone might find a way to decode the encryption.
Even if the connection between your computer and the website is encrypted, it does not guarantee that the website is trustworthy. Your privacy can still be compromised by the way the website uses or distributes your information.
Answer to Question 3:
With so many types of malicious software being spread around the Internet, it is important to be aware of what spyware is and what spyware does. Spyware is a general term used to describe software that performs certain behaviors, generally without appropriately obtaining your consent first, such as:
• Collecting personal information
• Changing the configuration of your computer
Spyware is often associated with software that displays advertisements (called adware) or software that tracks personal or sensitive information.
Trading tracking for services
That does not mean all software that provides ads or tracks your online activities is bad. For example, you might sign up for a free music service, but you "pay" for the service by agreeing to receive targeted ads. If you understand the terms and agree to them, you may have decided that it is a fair tradeoff. You might also agree to let the company track your online activities to determine which ads to show you.
What does spyware do
Knowing what spyware does can be a very difficult process because most spyware is designed to be difficult to remove. Other kinds of spyware make changes to your computer that can be annoying and can cause your computer slow down or crash.
These programs can change your web browser's home page or search page, or add additional components to your browser you don't need or want. They also make it very difficult for you to change your settings back to the way you had them.
