There is one more tab in the Internet Options window that contains security settings. It is the "Advanced" tab. Among numerous other settings there is a section for "Security" as shown above. The default settings are probably suitable for most people. One setting that I personally like to change is "Empty Temporary Internet Files folder when browser is closed." The default is unchecked and I prefer it to be enabled. It keeps the temporary files from building up. It also prevents any possible intruders from seeing where I have been.
