When you finish up with your bank, or your credit card, or your electric company, make sure you look up for that little button or link that says “Log Off” and click on it.  These websites have put lots of security in place but the session is still open. Even if you close the browser window your credentials could still be available for transactions. Any time you visit a website that has or has access to your personally identifiable information, or any of your financial information, make sure you log off and then close the browser window.
