Also known as UCE (unsolicited commercial mail), spam is unsolicited e-mail. Often, spam will relate to dishonest get-rich-quick schemes, bogus products, or invitations to pornography sites. Sometimes spam mail contains viruses as attachments. Prevention is better than cure. The following tips can assist you in reduce spam. 

• Be careful about giving your email address when filling in forms online.
• You could also consider using a separate email address for some public activities such as chat rooms, in order to protect your main address from spammers.
• Never respond to unsolicited email. Spammers will use your reply, even your unsubscribe messages, as evidence that the email address is valid.
• Never buy anything advertised in spam. Most of it is fraudulent anyway and successful sales only encourage the practice to continue.
• Never post your email address publicly on the Web. Spammers have ways to collect and use these email addresses.
• Always opt-out of company solicitations you do not want.
• Do not use an unsubscribe link from an e-mail.  By using an unsubscribe link in an e-mail, not only are you saying this is a live e-mail address, you are also have the risk of downloading malware that turns your computer into a proxy for sending spam.  Other variations of an attack places keystroke loggers on victims' computers, enabling the spammer to collect personal information - including passwords and financial account data - from the victim.  The links are now required by federal law, but conventional wisdom suggests "opting out" often has the opposite effect, because it announces to the spammer that the e-mail address is accurate and active.

The only sure-fire protection: just delete the spam right away.
