Correct answer: check the email address to make sure the message is really from your cousin
Be careful when opening unexpected emails. Spam or junk mail could contain viruses that can damage your computer. Even if you recognize the name of the sender, look at the "from" address. It could be a "phishing" message trying to trick you into downloading harmful software or revealing personal information.
Don't download suspicious file attachments or click on links. Flashy ads and strange messages could also contain spyware, which is used by people who want to steal your personal information and your parent’s credit card numbers. Talk to an adult you trust if you receive an online message that you are unsure about. They can help you figure out if it is safe, true or appropriate.
