Protect your hardware: Safety and security start with protecting computers. Install a security suite (antivirus, antispyware, and firewall) that is set to update automatically. Keep your operating system, Web browser, and other software current as well and back up computer files on a regular basis.
Use strong passwords: Make sure that your password is long, complex and combines, letters, numerals, and symbols. Ideally, you should use a different password for every online account you have. If you need to write down your password to remember it, store it somewhere away from your computer.
Be cautious about messages that contain links in e-mail or from social networking sites. Even links that look they come from friends can sometimes contain malware or be part of a phishing attack (attempts to collect personal information: logon and password and other indentifying information by pretending to be a message form a friend or a business). If you are suspicious, don’t click! Contact your friend or the business directly to verify the validity.
