Attackers spoof a sender’s name to fool people into opening attachments that collect personal information and forward it to the attacker. Malicious content also hides in email messages that use HTML or Rich Text. Read your email in plain text for added security.

Treat IMs just as warily as you would email.
Use Strong Passwords
Use a variety of letters, numbers, and special characters in your passwords, and the longer and more complicated, the better. Use different passwords for each account.

If an account supports it, use two-factor authentication. To get a handle on your passwords, consider using a password manager application. Many web browsers, such as Chrome and Opera, save passwords if this feature is enabled.

Third-party apps, such as LastPass, are also helpful. These act as browser plug-ins that monitor password entries and save credentials for each account. All you need to remember is the single password you created for the manager program.

Keep Abreast of Internet Scams
Don't open or click links in emails that tell sad stories, make unsolicited job offers, or promise lotto winnings. Also, beware of emails that masquerade as security concerns from your bank or another e-commerce site. These emails may contain links to malicious content.
