Spam is any kind of unwanted online communication.
The most common form of spam is unwanted email. You can also get text message spam, instant message spam (sometimes known as spim), and social networking spam.
Some spam is annoying but harmless. However, some spam is part of an identity theft scam or other kind of fraud. Identity theft spam is often called a phishing scam.
To protect yourself against email spam, use email software with built-in spam filtering. For more information, see Help keep spam out of your inbox.
