Use common sense and take a 'buyer beware' approach. If you don't know the sender and you're not expecting anything, don't open attachments. Never click on a link in an email, as it could send you to a fake website; instead, use the search engine (such as Google or Yahoo) to locate the site. Businesses like banks often post customer alerts on their websites if they have been targeted in a scam.
