Everyone gets lots of spam. We get some spam from idiot marketers, but most of it is either attempts to infect your computer with viruses, or attempts to scam you out of your money. We will discuss how to recognize fraudulent emails, and how to protect yourself.
When you see a suspicous email, look for the following signs:
Money for nothing? A thousand dollar give certificate for no work? can you make an easy living visiting restaurants as a secret critic? A million dollar check that just needs someone to cash it? All of these things are too good to be true, and are sure signs that someone is up to no good.
Here's an example:

Are they planning to give $50,000 to everybody on the internet? Probably not. More likely, if you click on this, your computer will get infected with a virus or your credit card information will be stolen. If something looks too good to be true, it probably is a scam.
Any email from your bank or anyone else offering you big money or asking you to get involved in a serious transaction, will know your name. Banks in particular are pretty fussy about this.
Here's a sample I received this morning:

The man who wrote this claims to have millions of dollars for me. But his email is not addressed to me personally. It's obviously a scam.
Have a look at the person who is mailing you. Let's say they are with Bank of America. Is the return email address at Bank of America? Let's look back at that last email and see who it is from:
Wow, that addres is at "live.co.uk". That's not part of the FBI. It's not even in America. If the return address doesn't match the sender, it's most definitely a scam.
Does the sender's email match the links on the site? For example, if the sender claims to be with Bank of America, are the links to Bank of America? You may want to review how URL's work to make sure you understand where a URL points.
Sometimes links can lie. To view a URL, place the mouse over the link and then look in the lower left hand of your screen.
For example, try this link:
Free stuff! Millions of Dollars in Free Money! Just For You!!!
If you hover the mouse over the link, it will show you where it REALLY goes.
Remember, the domain part of a URL determines where the server is located. Look at the following link:
http://iamascam.com/bankofamerica.com/real/really/supersecurity/bankofamerica.com/safe.html
This site is not located on bankofamerica.com. It's located on "iamascam.com"
This is nearly always the sign of a scam. Sorry, we're not racists here, but the Nigerian Scam industry is well known. For example, in the email above that claims to be from the FBI, it turned out I needed to contact someone in Nigeria to claim the missing $10 million. Is that a scam? Of course it is.
A Nigerian scam is someone who emails you with a promise of easy money, then asks you for some percentage of the money back, for expenses or whatever, and in the end, they get your money and you get nothing.

BEST REGARDS
Some typical variations:
Typically what will happen is they will millk you for as much money as they can for expenses, then vanish. It's that simple.
Another variation is that they will get you to give them your bank or credit card details, then drain the account and vanish. Either way you end up empty handed.
Scams like this usually involve a large amount of money from a dubious source. The idea is that you think you're onto a special opportunity, and you don't have to do much, and you get money for basically nothing. A person who is paying attention ought to notice right away that this is too good to be true, because it's always a scam. The dubious source is part of the scam. They don't want you to come after them, and they're supposing that perhaps by being involved in something illegal, you will not ask questions and will be afraid to go to the police.
Love Scams
Sometimes the scam plays on your desire for love/attention/popularity/do and at the same time your desire to do a good deed. You will receive an email from a poor but honest girl from the Philipines. Or the poor girl from Russia or the Ukraine or some other place known for pretty girls and bad finances. A girl will write you and tell you you're special (how did she get your name?) and ask for money for school, or support, or lawyers, or whatever. It turns out she's married, or has grandchildreny, or has 35 boyfriends all supporting her, or all of the above. She may even be a man. There is an entire INDUSTRY of people who make a living doing this. Really.
