Never click on links or download files in emails from unknown senders

Whenever you open an email, first look at the source. Who’s sending it? Do you know them? If the source looks at all unfamiliar, proceed with caution. In the body of the email, there might be links or attachments with a message prompting you to click or download them. These files might contain malware. Some malware emails are advanced enough to not be detected by antivirus software.
