Staying safe on Yahoo
Choose a long, memorable password
A password is like a toothbrush: Choose a good one, don't share it with anyone, and change it at the first sign of a problem. Your Yahoo password must be from 8 to 32 characters and contain uppercase and lowercase letters and a number. It cannot contain your first or last name or your Yahoo ID. Think of something that's easy for you to remember but impossible for others to figure out. Learn more about creating passwords and keeping them safe.

Keep your Yahoo account information updated
Chances are, something in your life has changed since you first created your Yahoo account. Maybe you've moved to a new house or changed phone numbers. Make sure the contact information in your account is current so that if your account is ever locked for security reasons, you can easily verify your contact information with our Customer Care team.

Keeping yourself safe online
Beware of email scams, especially password "phishing" scams
Scams abound on the Internet, from financial rip-off schemes to password phishing scams in which fraudsters try to steal your password so they can unlawfully access your online accounts.
Ignore or report as spam, any unsolicited email urging you to invest in stocks or participate in advance fee fraud or Nigerian 419 scams, where you pay a fee now for guaranteed riches later. If you receive an "urgent" email from a bank or other online service, be suspicious. Most reputable services will contact you by postal mail if there is an issue with your account. Do not click any links in these emails; instead, type the web-site address directly into your browser's address bar.

Be cautious about what you share about yourself online
The Internet can be a great place to make new friends and find people who share your interests. But remember that online not everyone may be  who they appear to be. Be careful of the people you trust online and what you share with online strangers.
Think twice about the information and photos you share on blogs, social networking sites, message boards, and other web sites. Scammers can get this information as easily as anyone else, and they can use your personal information for ill.

Be careful when using shared or public computers
If you share a computer, whether it's in a public or private setting, make sure to sign out when you're not using an account. And learn how to clear the browser's cache after browsing the Internet.  Remember that using a shared computer is always riskier than using a computer that no one else has access to.  Learn more about using shared computers.

Keep your computer secure
Always use antivirus and antispyware software
Antivirus and antispyware software can detect many — but not all — forms of malicious software before they have a chance to affect your computer.

Keep your software up to date
You can prevent many problems by regularly checking for and installing updates for your operating system, browser, messaging software, and other programs. Learn more about protecting your PC.
Be careful which programs you download or install on your computer. Malicious software (viruses, worms, Trojan horses, and spyware) often masquerades as legitimate and even useful software. Think carefully before installing or running new software, especially anything unsolicited.
